Oh, no doubt. It's just that Nehalem was a bit too soon (and I was more broke then) and afterwards it just didn't seem that exciting - I thought I'd do it with Haswell, what with the TSX, AVX2 and what not, but then the -K series got crippled for differentiation reasons, and the heat issues, and overall focus on energy over performance and just... meh.
And while I'm sure the processor is limiting the graphics card somewhat, as far as I could tell, it's not that much.
Let's say my overclocked Q6600 is roughly as fast as the AMD A10-5800K (good job, AMD!):
The A10, while being the slowest of the bunch, delivers just 10 fewer fps in Crysis than the 4770K:
yeah it's worse in the worst case but again, just meh.
But I am going to do it next year for sure, so I hope Nvidia is working hard on Maxwell as well!
