Hi all, i am thinking to upgrade my aging GTX 580 to a 780. but will my i7 930 @ 3.8 ghz will be enough not to bottleneck the 780?
further system specs :

12 GB ram
160 Gb SSD intel G2 postville
X-Fi fatality PCI 64 Mb
Bigfoot killer Nic 2100
GTS 450 for physx
2x raptor 600gb raid 0 for programs.

Thanks for replies!
 
Gonna bottleneck it man, oc that bugger up some or swap it out for a cheap 2500k oc'ed.

It probably will do to some extent, can you search the 3dmark database for 930+780 results and see what that gets compared to say 3770K+780 or 3820+780 combos?

e.g. a friend of mine runs a 580 with a Q6600 cpu and he only gets about 50% the FPS of a more modern CPU with that video card, he is a bit short of cash and he would like to upgrade but since it runs call of duty which is all he ever plays then he is satisfied with it for the time being.

I'd say if your getting 75%-100% range of performance compared to the higher speed chips then live with it for the time being.

If your getting 50%-75% then yes you are probably a candidate for an upgrade.

I think generally the best bang for the buck is to change the motherboard+cpu and video card every two years but alternate the purchases every other year and that way the newer component helps out with the older one, you'll never have a cutting edge machine but then again you'll never have one that's at the bottom of the pack either.

Thats my 2 cents worth, hope it helps.

Cheers

P.S. Given you can run SLI why not just get something like two 670's instead? or even buy a second hand 580 and SLI that with your current one? you have a board that is built for that sort of thing.

He'll need even more cpu power for SLI :\ I'd say he overclocks it to 4.0 - 4.2 or sells and gets a 2500k that should minimum hit 4.5 (most likely 4.7+).

The difference between 3.8ghz and 4.0 its not so great to say it will bottleneck at 3.8 but not at 4.0 compared to run his 930 at stock... 3.8ghz its a nice speed to handle fine the GTX780...
 
you should be fine.

no offense, but some of you take those 640x480 CPU benchmarks too serious.

there is very little difference in CPU performance at 1080p or higher, I've seen tons of benchmarks.

Depends on the game. There are differences, probably not huge in some games, but in certain games there can be.
 
what resolution? that's the key. my 920 @ 4ghz wasn't bottlenecking my Titan in surround, but certainly would have at 1080.

Yep I can believe that, it makes funny reading these people that don't understand CPU/GPU scaling.

Its like the first poster is nearly always wrong with this type of question lol

Once again largely not true.


At a stupid low1024x768 resolutions or lower sure the [email protected] may be a bottleneck in some games with a GTX780, BUT you will be getting maybe 150FPS instead on 190FPS with a faster processor (and that's not going to make a diff), at higher resolutions CPU becomes less of a bottleneck factor.

For something to do just googled Metro Last light possibly the most demanding game ATM using a TITAN

Even at the modest resolution of 1920x1200 where we would expect to see the CPU bottle-necking, the low clock STOCK [email protected] is only a minor bottleneck, bump that puppy to the OPs 3.8 and she would be around the top of the list.

http://www.techspot.com/review/670-metro-last-light-performance/page6.html

As you increase resolutions CPU bottle-necking becomes even less of a factor.


Synthetic benchmarks sure upgrade, but who cares about Synthetics

I would estimate in 95% of modern games a faster CPU than a [email protected] is not going to help, that last 5% a tiny bit :p

School is out (nerdy geek high fives all around!)

I just personally wouldn't run a cpu less than 4 ghz nowadays, just personal preference I guess... it's just safer to fall back on in case a particular game is more cpu intensive. Thats what I meant. Of course at 1080p he should be decently fine at 3.8 maybe within a few of a higher clocked cpu at 1080p. Throw in another or two gpu's though and it changes alot. There is some huge differences.

So are you saying we should go FM2 ? :)

Someone had to finally say it. They were using the i7 920 to benchmark games and video cards for along time. That generation still has quite a bit of life to it especially if you're mainly gaming at 1080p.

After all said and done the 920 is still in the i7 family.

Intel still hasn't really released a CPU with different architecture.

exactly. if it hadn't been for the ridiculous amount of heat my 920 put out at 4ghz, I would have held out longer.
