Can't decide whether to build an AMD or Intel gaming rig. This is for current gen games and I want the highest performance out of my processor. haven't decided on other parts yet, but for comparison's sake, assume:
7970 radeon cards crossfire
8gb ram
750w PSU

obviously I havent picked a board yet. and advice?

EDIT: Just to add a little more, also compare the FX-8350 please.

3570K for sure. It's better than the AMD chips in most games and uses a lot less power doing it.

If you do go AMD, definitely go with the 8350 because the 8150 really isn't competitive at all.

Depends on what ELSE you're doing with the computer.

If you're doing something like video rendering, or any other heavily multithreaded application, the 8350 wins.

If you aren't, or the applications you use only use a few cores, the 3570k wins.

The other thing to consider is power draw and thermal limit - in a large computer, it doesn't matter, but if you do something like what I do, and build small form factor computers... well, let's just say that for my part choices, I'm heavily biased towards Intel and Nvidia, just because of how hot AMD's products run.

Part of the reason I'm curious about AMD is because their chipsets allow full 16x 16x when running crossfire. Intel's z77 chipset on allows 8x 8x on most boards. AMD runs in PCIe 2.0 speed, but as Ive been told, the difference between 3.0 and 2.0 is negligible. any thoughts?

There really aren't any cards out there at the moment that can even saturate PCIe 2.0 much less 3.0. Unless you plan on getting something like Crossfire 7990's, I would say the difference is negligible.

As it is for current gen games, then go with Intel i5 3570K -- it is better than both FX-8350 and FX-8150.

The HD 7970 is an excellent card, but you don´t need to crossfire just now, but if you do in the future, then I´d recommend you a 850W PSU, as you might want to overclock the CPU.

8GB RAM is enough! :)

Intel Core i5-3570K http://www.newegg.com/Product/Product.aspx?Item=N82E16819116504
GIGABYTE GA-Z77X http://www.newegg.com/Product/Product.aspx?Item=N82E16813128546
SeaSonic M12II 850 http://www.newegg.com/Product/Product.aspx?Item=N82E16817151108
G.SKILL Sniper Series 8GB http://www.newegg.com/Product/Product.aspx?Item=N82E16820231460

I´d add a SSD too SAMSUNG 840 Pro Series http://www.newegg.com/Product/Product.aspx?Item=N82E16820147192

It would be crossfire 7970's. But if that's the case, and if power wasn't a problem, would having two 7970's and a FX-8350 beat a single 7970 and 3570K? I kinda want this crossfire config. What's the performance difference between the two CPU's? (borderlands2, SC2 for example)

Yeah 2 7970's and an FX-8350 would beat the 3570k and a single 7970 but the price difference between the two CPUs is around $20-30, hardly enough to afford a second card. The Intel chip dominates in Starcraft II.

The difference between PCIe 3.0 and 2.0 is negligible for any single card because no single card yet bottlenecks on 16 lanes of PCIe 2.0.

However, PCIe 3.0 has double the bandwidth of 2.0, which means x8/x8 of PCIe 3.0 is exactly the same as x16/x16 of PCIe 2.0... which means there's actually no downside to z77.
