Also your comment on CPU's - The reason your CPU is fine is because CPU's havent moved much since Nehalum.
You have 8 threads running at 4.2ghz. Really wont make much difference.
CPUs architecture changes have never really resulted in large performance increases, due to the nature of their workload which tends to be more serial in nature compared to the parallel nature of the GPU.
The improvement from the P4 to Conroe was on average 20%, with certain workloads seeing improvements of up to 30% and even 40% better IPC.
Nehalem to Ivy Bridge is approximately 20% better IPC (with greater improvements for SIMD optimized apps), but I was also counting on the higher clock speed enhancement as well.
Most of my improvement would be in the minimum frame rate. I would expect at least a 5 FPS improvement in minimum, and perhaps a 2 or 3 in maximum frame rate.
At any rate, I have no intention of upgrading to Ivy bridge. I'm jumping on Haswell, which should provide me with approximately 30% faster IPC over Nehalem.
Also you wont gain 10 FPS in Crysis 3 even if you did change. There is no CPU bottleneck in that game. Its all GPU.
How many times are you going to repeat the same lie over and over again that I said I was going to gain 10 FPS?
Also, Crysis 3 is very demanding on the CPU, and is in fact one of the few games that can actually utilize a hexcore processor. Even at VHQ @ 1080p, the CPU makes a tremendous difference to performance:
