    What do you think about this?

    I crave more computational power. I could swap my 6800k with a 6900k without having to take apart my pc, but then I'd probably be stuck with an unsellable cpu.

    Or I could just buy a new MB with a 7820x for a bit more, but stand a much better chance of selling my old ones. So basically bribing the cost to a similar level.

    ?

    Or I might just do nothing, spending $600 for 2 more cores doesn't sound all that good when I come to think about it.

    If you have a Microcenter near you, then go for the 7820x. It's only $399.99 right now, plus you get $30.00 off when purchased with a motherboard. I upgraded from a 6800k @ 4.3Ghz to a 7820x @ 4.7Ghz and I think it was worth it.

    Life is short. Have a little fun. :happy:

    My thoughts for the hardware enthusiast:

    I too am on 6800k and I am wondering the same things.

    If you can justify upgrading frequently I say go for it.

    Eventually you will be in the same situation with the 7820x as are now with your 6800k.

    The 7820X will be the old 5820k and so on.

    With ryzen, high core count usecases have become much more affordable. With the rate new products release 1 upping the last, upgrading for the sake of extra cores isn't as easily justified.

    Gone are the days of 4 cores reigning supreme.

    My personal opinion for enthusiasts who like to upgrade is to do just that. Upgrade, but don't invest so much money that you can't justify upgrading to the next best thing. Clock speeds, IPC, memory speeds, and featuresets will improve, and there is nothing a high end part can to do to prevent its eventual obsolescence.

    So stay on the newest gen. Get the good value part. Later go on to sell, and upgrade while your parts still hold their value. Lets parts like the 6950x be a lesson that high end parts lose their value faster than a buying a new car would.

    However, much of this advice can vary depending on the specific need of your use case.

    Well I regret upgrading from 3820 to the 6800K also. I don't think I got my money's worth. And I had to replace RAM as well then, for no good reason. Maybe I just wait and see what happens when they refresh skylake-x and if it will be on x299 or not.

    Personally, I thought x299 was a disappointment. I ended up selling my 7820x (then again, it was closer to $550 when I bought it, not $399). I'd just stick with your X99 setup.

    You should get the Ryzen 7 2700X

    ...basically the same performance as the Core i7-7820X for 50% less $$$

    The 2700x from AMD and 7820x form Intel have shown to be VERY close in performance in regards to both productivity and gaming, so how is that "shilling". Sure you can hit 4.7 ghz on the 7820x, but it takes a lot of cooling, will still run hot and use a good amount of power. It is a setting most will use just for benching, not 24/7 use. Overclocking the 2700x to its max is fine with the stock cooling and 24/7 use.

    How is it 50% less? It cost a but $125 more for a better cpu and platform.

    Since you already have quad-channel RAM it wouldn't be a bad idea to move to a 7820X rig if you need the extra cores. Most 7820X will reach 4.7ghz with fairly low voltage and they don't take exotic cooling to maintain temps. Your current system is reaching its sell by date so if you are going to move on and get something decent for it the time is now. Otherwise, just drop in a 6900K and use it for a couple of more years to reach a decent ROI.

    No matter how I calculate it it is not 50% less. If you get a half decent AM-4 board that costs almost as much as an x299, and still offers less features than those. And the Cpu is about 30% less only currently. And it's not really the same performance, is it? Even at stock the AMD falls about 10% short. And it's overclocking potential is much more limited. I had a streak of bad luck with the silicon lottery in the past anyway. So I'm not getting something that doesn't even have a high potential. Plus I'm not about to go mainstream, HEDT platform or bust.

    You know damn well that that low end B350 motherboard is nowhere near the level of the entry level X299 boards like the asrock you picked. I've owned Asrock HEDT boards before, they're damn good. So don't scrape the bottom of the barrel.
    Also adding the cooler to the price is a nice try, but since I already own multiple coolers it's quite pointless. I'd never use a bundled cooler anyway, so I was quite happy when Intel decided to no longer bundle their weak ass cooler with hiend cpus.

    Local lowest price for 7820x : 520USD
    Local lowest price for 2700x: 360USD
    That's only 30% less.

    At the bare minimum you need to pick an X370 to even have a comparison. But you can't since one is HEDT the other will still be mainstream. Even if you pick a hi-end X370 you'll still not match even the lowliest x299. So please don't waste your time trying to argue they offer the same value. Cause they clearly don't.

    If I was looking to build a system for someone else who is very price sensitive, not an enthusiast and not planning to OC, I'd definitely consider the Ryzen.

    If there was a cheaper ATX motherboard for Core i7-7820X, that would have been used for comparison.

    Fact of the matter is that there isn’t.

    A B350 motherboard handles the Ryzen 7 2700X just fine.

    There is no need for X370/X470 motherboards unless you are looking for some specific features.

    Also, since Core i7-7820X doesn’t come with a cooler, one would, of cause, have to factor in the cost of the cooler.

    Just because you already have one doesn’t mean that everyone else does.

    Reading through this again: from a price/performance perspective, Intel HEDT doesn't make much sense over consumer Ryzen if you're only going to eight cores, but it is still a tad faster- however, it sounds like the bigger issue is that the consumer platform is more limited in terms of stuff like PCIe lanes (and powered slots) and maximum memory.

    If one is looking for more PCIe lanes, it’s no contest: Core i7-7820X wins

    ...but if one is just looking for Core i7-7280X’s performance, Ryzen 7 2700X offers that for a fraction of the cost

    But the thread was started by me, and not everyone else. And your everyone else I'd wager is not that big of a group on this forum who don't already have a good cooler. Sure if you're completely new to building your own PC and don't have any parts you need to factor in the cooler. But even then I doubt a true enthusiast would go with the stock cooler for any CPU.

    Of course there is no need for a X370, as there is no need, for quad channel memory support, or more pciex lanes either. Now if you're just looking at a barebone system that just works, then sure the Ryzen is better value for the money. But it's definitely not the same value for less money.

    You have to factor in that the Wraith Prism is better than most (all?) other stock coolers out there and is probably on par with some of the popular budget coolers.

    If you have other coolers laying around, just sell them.

    Or you can sell the Wraith Prism. It's selling for $40+ on eBay right now.

    Of cause that is to say that you even use those features (which you did not specify). If you have more PCIe lanes, that doesn't mean anything if you don't use them.

    LOL, now I'm getting prosecuted whether I really need the features I Want? This is getting ridiculous.

    I have two Graphics cards at the moment, so that's already 32 pcie lanes. and a raid card which also uses 4 lanes. Also I'd very much like to update my aging OS drive to a decent m.2 one eventually. Therre goes a few lanes as well. And I'd like to use 4 channel memory when the prices become what I consider reasonable and upgrade to 32GB. Sure that might never happen, but I'd still like to have the option.

    As for selling the cooler, I just can't be bothered to deal with selling low value stuff, it's more hassle than it's worth. That's why I haven't sold my 140mm AIO cooler either, when I've been using a NH-D15 for almost a year now.

    How much for the 6900k? Or even a 5960X?

    Responding to your original post before the side-track...

    What are you doing with the machine that you'd see a beneficial jump for? Is the real question. And is that bump worth 600 bucks out of pocket? Would you resell your 6800k to gain some back, or keep it as a spare just in case?

    The deal someone posted with the 7820x price at 399 + 30 off with board is a great deal, and now you're on a DDR4 platform, you don't need to change RAM, just CPU/Board. It'll be less of a 'regretful' purchase than your 3820 to 6800k because the RAM cost isn't there.

    But realistically, is it a case of 'want' more power, or 'need'. And whether that want is worth the cost.

    I'd argue if you're doing work on your machine that you make money from with renders/video editing, and the time saved with a new CPU will long-term provide a good return then it's worth it.

    If not. Save the dosh and stick with what you have.

    If i were you i wouldn't even consider the 6900k at this point. If you really feel you need 8 cores you should either buy a 5960x (which you can find for $400ish used) or a new ryzen system.

    I do a lot of rendering and video editing as a hobby, that's why I can use all that I can get. But it's not something I make money from. I was thinking about whether I should be taking commissions but as soon as money gets involved there is obligation, and that would ruin it.

    Unfortunately US deals don't apply to me as I'm in the EU. Everything tech related is cheaper in the US even without deals I get really jealous sometimes. Here we never get good deals on any parts. Probably because vendors are small so they can't afford to sell bellow msrp. Not even for a limited time. I've seen deals in the US where the hardware would still come out cheaper including shipping for $200 and about 35% customs fees than the cheapest avaialable vendor locally. The only reason I don't order from overseas is the warranty.

    Ah fair enough. I'd still consider stirring on it for a while and see if you really want to make the change. I'd probably consider a new platform rather than the 6900k. Alternatively any cheap Xeons on ebay or something?? :p.

    I'm from Australia so know all about pricing issues haha. Same issue that warranty trumps cost in the end..

    Not in the least bit. Microcenter in my opinion is 100x better. Frys is like ... "we don't give a shit about nothing especially customer service".

    Good stuff in that thread. Most of my stuff is also posted in there. No bull shit, it is a bad ass 8-core....if that is what you are looking for.

    Month late.. I'll toss my 2c worth in as I've been having the same conversation with myself, my ole Haswell rig in siggy. I'm going to wait for the next tic/toc outta the CPU market. My current setup has just enough PCIE lanes with SLI and an m.2 boot drive where I do not feel I'm shorting myself on performance. None of the games I play feel like they are suffering due to a slow CPU. Granted I've been feeling the upgrade itch just because there are new shiny toys out with Ryzen x2700 and even the Intel 8086k has been getting my attention. At the end of the day neither of those 2 platforms has enough PCIE lances to make me want to migrate off this x99 rig even though SLI should see no performance drop at 8x8.

    right now on ebay the 5960x is about 350 and theres one 6900k for 400. seems pretty good if you already have an x99 setup, makes me want to upgrade from my 6850k

    IMHO the X99 CPU's are still relevant. the chipset has a decent feature set as well. $350~$400 for a decent upgrade where you do not need to refresh your entire system (offset by selling old CPU) seems like a no brainer to me if you need a few extra cores.
