So its a real resource hungry game?? I planning to get it but what the use if it won't run on my PC.
It depends on whether you need to max it or not, to max out this game @ 1080p in DX11 mode, max aa, you need 2.8Ghz+ Quad core processor(or 3GHz+ dual cores with HT), 4GB RAM and at least GTX580(still can't do PhysX) or a similar or more powerful card. To use PhysX you need to use a secondary card(GTX460+) as even GTX580s cannot run this game maxed out with PhysX, if you go multigpu then you need GTX560 SLI atleast.
This game is more stressing than Crysis and likewise visuals are very good(mega high res textures and awesome lighting), visually this game is second only to Crysis.
However if you max this game out in DX9 mode you can do with GTX570 or HD6950 @ 1080P(no aa and no PhysX).
I can play this game @ 1680x1050 no aa, DX9, normal settings(medium) but as soon as I go high/very high or DX11 its unplayable, DX11 and aa turns this game into slide show for me.
