mmm DX10, but whether you upgrade your ram and such it wont have an impact on whether you can run DX10 or vista when it comes out, im upgrading mine now and besides after a year after launch when i get vista, ill probally need to upgrade again.
Dude, you don't really think thats real do you? The water is totally fake, you can see they overlayed a photo of real water over the "DX9" screenshot, check out the reflection irregularities, they are the same in both.
Also, the edges of the water are totally messed up, whoever made that fake screenshot is a total n00b.
