S!
My bet is that SoW will bring to it's knees ANY brand GPU out at that time it is released. IL-2 did that back in the ancient times and so will SoW
If you make a game engine, make it last like IL2 did. SoW will not be any different..just my 2cents.
The article was interesting, thanks for linking it. Not starting a flame or fanboi war here, but I would not expect the Fermi to be a cheap card, especially if you want the higher end version of it. Same applied for ATI, their flagship 5970HD costs quite a bit...
