I'm getting a custom pc and I'm not sure wich one of these 2 gpu's I should pick. I know the amd is a little bit faster and has more vram but I'm a huge borderlands fan so I guess it would be nice to be able to run Physx. Also I've heard from a friend who has a nvidea graphics card that the drivers are really good. Both are msi cards and have the same twin frozr cooling system. What do you guys think is best for me?
