Yeah, the opinions on the i5 vs 8350 are definitely right. The AMD simply has weaker cores, unfortunately. It will fall behind on several games.
As for the opinion on the 960, it's a bit beyond the price of the 270X. The 960 is around $200, while the 270X can be found around $160 right now. The 960 is probably worth the extra $40, but then you might as well go $10 more and get a 280X.
