ATI versus NVidia

[sfmadmax]

I currently have a Nvidia 8800 GTS 512mb

I can play the game over the sea on 1920x at low settings for everything, except model and effects I turn to high. It's somewhat ok. 20 - 25fps. I imagine the majority of the hold up is my Graphics since I have a I7 3.2 with 12GB system ram.

I was planning on buying a Nvidia GTX 580 but after reading all the hype here the game takes advantage of video ram. I might hold off until the patches come out and then see what the fellow nvidia users say !
