Best option need help

What is better for gaming and not rendering and stuff like that. Games like Arma 3, BF3, BF4, Skyrim and DayZ.

I5 3570K + GTX 660 TI  2GB GDDR5 Superclocked + 8GB 1600Mhz RAM

VS

AMD FX-8350 +AMD Radeon 7950 3GB GDDR5 +8GB 1600Mhz RAM

And will either of these setup's play Skyrim at 1080p Ultra at like 50-80 FPS Average. There both about the same price.

What's your total budget? For gaming only, a high end CPU like an i5 or 8350 is only usefull if you have a very high end GPU like a 7970 or a gtx 680.

I could get a 7970 3GB GDDR5 for like $80 more.
