I don't have an "alliance" per say because I have owned both and I just buy the best deal (As every sain person should).
However I will say that I heavily favor AMD for these reasons:
-Price/Performance is generally INSANELY in favor of AMD. 280X = 770, and yet the 280X is $100 cheaper and has more than enough RAM. Only an idiot would buy a 770 or 780 right now.
-Nvidia skimps on VRAM like crazy. 580 1.5 GB while 6950 had 2? In the BF4 beta I see Nvidia people complaining constantly that their 2GB is not enough. Well than you shouldn't have bought that stupid card.
-SAPPHIRE >>>>> EVGA. Every, and I mean every EVGA card me, or my friends bought broke within 2 years. NO SAPPHIRE card I have seen has ever broken, and even when abused by excessive overclocking.
-Nvidia Drivers for me were a complete mess during the 500 series.
That's about it. Say what you will since a lot of what I said is opinion, but seriously is that extra 18% performance a 780 has over a 7970 worth $350? No.
