Closed Cpu bottleneck GTX 670 SLI Tags: Graphics Cards Gtx Bottleneck Intel i7 CPUs SLI Graphics Last response: June 4, 2012 1:25 PM in Graphics & Displays Share witcher_chaos June 3, 2012 4:12:49 PM Hi, will there be a bottleneck on my i7 920 @ stock if I use 2x GTX 670's? If yes, then will it still bottleneck if I OC my CPU? Thanks!

Are you contemplating a change from what to what? I suspect that if you are planning to upgrade from one GTX670 to two, the answer is no. As a rule, the graphics configuration is mote important than the cpu. Depending , of course on the game. Your i7-920 is a competent cpu chip, and it can be overclocked easily. To help clarify your options, run these two tests: a) Run your games, but lower your resolution and eye candy. If your FPS increases, it indicates that your cpu is strong enough to drive a better graphics configuration. b) Limit your cpu, either by reducing the OC, or, in windows power management, limit the maximum cpu% to something like 50%. Go to control panel/power options/change plan settings/change advanced power settings/processor power management/maximum processor state/ set to 50% and see how you do. If your FPS drops significantly, it is an indicator that your cpu is the limiting factor, and a cpu upgrade is in order. Another way to do this test is to OC a bit and see if your FPS increases, indicating that the cpu is a limiting factor. It is possible that both tests are positive, indicating that you have a well balanced system, and both cpu and gpu need to be upgraded to get better gaming FPS.

I would imagine that a single GTX670 would perform a bit better than sli 5850 cards, and do it with ledd issues from dual cards like heat issues, microstuttering, and minimum frame rates. If you will be using only a single monitor, I think you would see diminishing returns from sli GTX670, even with the strongest of cpu's. Instead of spending $800 on two GTX670 cards, I think you would be better off to spend $500 on a GTX680, and the remaining $300 on a 2500K or 3570K and a Z77 motherboard. Offset that with the sale of the GTX580 cards and the i7-920. witcher_chaos June 4, 2012 8:37:01 AM Best answer selected by witcher_chaos.
