Just throwing this out there to see if anyone has any input, as i think what i've got selected makes sense, but who knows, there could be a variant i havent considered.

Right now my main flight sim rig (and rendering for astrophotography) is an 8700k overclocked at 5gh, ram at 3200mhz and a 1080ti graphics card.
I get pretty ok results as is, with flight sims (xp 11 and newer ones) and vr (oculus rift S), though the reverb v1 had some issues performing, so i stuck with the rift for now.

I have a second living room setup using a 1080 card (hybrid) and an ancient 4790k cpu. So the main purpose of this upgrade is to simply move the 8700k and 1080ti card into that machine (and the secondary part of all this, likely get a 3xxx series TI card once released for the main rig, assuming the prices are about the same as the 2080ti currently). I did briefly test 2080ti over 1080 on my rig and for the most part there was very minimal gains, but that might be changing as sims are changing a bit now.

So here is the equipment i had in mind, i've considered lower cpus but i feel the extra threads if only 4 are valuable.

Current cpu 8700k (passmark 13864 when not overclocked, i did get a delidded one from silicon)
Ones i ruled out:
i9 9900k (passmark 18894)
i7 10700k (passmark 19738)

i9-10900F (unsure on these other variants of the k)

i9-10900K up to 5.3 ghz (i assume only on one core at 5.3)
Silicon lottery $589 (another 50 to delid, guarantees 4.9 across? )
https://siliconlottery.com/collections/all/products/10900k49g?variant=32927024840790

Ram:
3600mhz ram (likely can overclock, to what not sure)
https://www.amazon.com/G-Skill-PC4-...DDR4-3600&qid=1595872606&s=electronics&sr=1-5

MB:
Asus rog maximus xii hero
$389 https://www.amazon.com/ASUS-ROG-XII...ASUS+Z490&qid=1595872807&s=electronics&sr=1-3

The lesser rog strix probably not as good to overclock i'm assuming ($289)


My existing cooler is this thermaltake:
https://www.amazon.com/dp/B00MPIDYTO/ref=pe_825000_114212990_pe_825000_114212990_n_id
360mm triple fan
Pretty sure wont work with the new CPU, so ill need some sort of newer version (any thoughts or recommendations on this)
I cant even use this on my living room rig, not enough room, so ill likely go corsair smaller system on that or even air.

Any thoughts on any of this, or any recent experiences with this cpu + mb combo?
Thanks in advance

Actually, your cooler is technically compatible with your planned new CPU. All mainstream Intel CPU platforms, from the earliest LGA 1156 of 2009 to the present-day LGA 1200, use exactly the same CPU cooler mount.

And since you're going to buy a new GPU for that planned build anyway, then it doesn't really matter which of the 10900 variants. The 10900F is IMHO a bit too expensive for what you get, especially since it is a locked CPU (unlike any of the K versions) with its integrated Intel graphics permanently disabled during manufacture. That leaves the plain 10900 and the 10900K (the 10900KF, like the 10900F, has its iGPU permanently disabled in manufacture, and thus all of the F CPUs require you to buy a new discrete GPU right away in order to be at all usable).

Also, if the i9-10850K is available for less than any of the 10900s, then go for it. It is just a slightly slower-clocked (by 100 MHz all-core) version of the i9-10900K.

And unless you already have or are buying a new graphics card right away, skip the F-series CPUs. If you do end up buying one, and you have not bought a discrete graphics card at all, then you will not have a usable build at all until you buy one.

Thanks,

Thats good to know on the thermaltake, then i just need to get a slimmer cooler for the living room rig.

Yeah i've been holding off on the new gpu till the dust settles on the 3000 series, hoping for a similar price point but newer (maybe requiring new psu from what i read, but maybe not).

Not really seeing any 10850k available at the moment.

I guess my biggest unknown is on if its worth it to grab a silicon lottery provided 10900k that they hand picked to "perform better" and pay the extra 50 to delid, if i could get at least 2-4 cores running at 5.3 max that would be a bonus and the rest at 4.9 (assuming the newer sim takes advantage of the multi high clock rate cores, otherwise one single one is enough and i think it will, ala fs2020).

I don’t see enough FPS gain per $ right now for my sig rig.
I’d wait for ampere at whatever price tier you’re comfortable and reassess your upgrade.
I sold my 1080ti, using a placeholder 2060 and framerate reduction in the games I play squarely bias towards gpu power being the deciding factor.

Take a look at this:

You can always look at the 10600and hope you get one that overclocks well (in all areas).


I would also avoid the F variant, the iGPU is nice for troubling shooting issues. Also, I don’t know if it really improves clocks/temp.

Yeah i guess the good ole 8700k is still good in many ways.

I might consider just finding a used 8700k and motherboard/ram and putting that in the other rig that has the 4790k i guess (and doing a simple 4.7 or so overclock maybe something like 2800 on ram, rather than my current 5.0 and 3200 esp if its running on air). Though really it might save $400, but $400 is 400.

I'm actually thinking my old hero board with the 8700k might benefit from upgrading the ram from the 2400 gskill i have at 3200mhz to maybe 4000mhz using something like one of these gskill's that have samsung bdie?:
https://www.newegg.com/g-skill-32gb-288-pin-ddr4-sdram/p/N82E16820374012
pc4 3200 ddr4 4000
F4-4000C17D-32GTRSB
$256

If i could get to 4000mhz that would be a substantial improvement over the 3200 i'm at now (when i jumped from 2400 to 3200 i gained 8 fps in most heavy hitting sims, i think at least)

I could then look for the used 8700k and board for the other machine.

The majority of games I have don’t use more than 4 cores. Some use 6, I have yet to find one that uses all 8 cores to their capacity. Sure if you’re streaming and not using hardware encoders, but I am not.

This being the case (for gaming purposes) the 8700k is more than adequate. The next step up is the 10700k/9900k. My 9900k is overclocked, and it’s cores can hit 5.1ghz with relative ease, maybe I got lucky? Really for flight sims afaik you need single thread performance, and either of these chips will work, the question is whether 100mhz-300mhz will make that much difference. I would say not.

I assume at 5ghz you have AVX offset at zero and your cache running at 4.7ghz?

Newer Fs2020 uses more cores, at least i think.

I do alot of astrophotography rendering which uses as many cores as it can, so a jump to the 10900k seemed nice (though for the price of around $1k not so much for all).
Thats why now i'm thinking maybe just getting a used 8700k for the other machine and/or a better ram set that can hit 4000

My cpu is actually set to 46 for cache and -1 for avx right now (at 5ghz).
