The CPU still matters.
The argument "well what about when it's overclocked, etc etc". The benchmarks are performed at stock speeds, obviously. That means the 8350 has a 600MHz advantage over the Sandy/Ivy/Haswell.
Overclocked, you can get a 20-35% linear bump with the Intel processors. With Vishera, it's more like 10-25%. Now, where things really start to go wonky, is that Vishera will be using 225-275W when overclocked, and also requires a decent motherboard. So you end up spending a bit more with 8 phase power compared to 4 or 6 that you can use with Intel.
As much as I like AMD they don't make sense to buy.
