How much difference is there in performance between lets say i7 2600k and 8120 FPS wise.
No. Bulldozer will not be better when games require more than 4 cores. This can already be seen in Shogun 2:Total war benchmarks. Shogun 2 can use at least 6 cores... I dunno about the full 8, but it certainly uses 6 (check out bit tech's 3930k review, where the 6-core sandy bridge-e processors get the highest score).
You can see here:
That an i5-2500k and even last generation Intel processors are superior to bulldozer even in a game that uses more than 4 cores (actually the only game that uses more than 4 cores that I know of, heh). Until the last test anyway, when the graphics card holds all 3 processors back to the same point. This is actually one of Bulldozer's better showings in CPU limited games... the answer to how much difference FPS wise is: a big difference in favor of the i7-2600k in games where CPU matters. The same performance if your graphics card setup can't cope with your current game.
@Bluestr Which brings up the following point: all those benchmarks showing Bulldozer or AMD as good as Intel in gaming are cases where graphics is limiting performance for both processors. In any case where your CPU is going to make any difference at all in performance, Intel clearly wins - at any price point.
AMD can be better for multi-threaded applications at some middle-low price points. But even then sandy bridge performance is close.
Edit: Bit Tech's Shogun 2 benchmarks showing no benefits of hyperthreading in Shogun 2:Total War (identical i7-2600k & i5-2500k scores) but an ability to use 6 genuine cores. This is just about the only review where the 3930k will out perform a quad-core sandy bridge in gaming.
Shogun 2: Total War is also one of the most hardware-demanding games on the market today for both CPU and GPU, as good an indicator of theoretical future performance of games using more than 4 threads as we have at the moment. Not to mention you'd probably be considering a new processor by the time heavily multi-threaded games became common anyway (because it will be years down the road).Edited by MisterFred - 4/17/12 at 8:10am
