Yeah that is a great budget system....i dont know how strapped for cash you are...but i would have gone with this http://www.mwave.com/mwave/viewspec.hmx?scriteria=AA39230
because its as good as the 6800GT at all res settings and its 199.99.
Someone else said they found a X850XT for 199.99 if you can get that deal get it. If not get the GS.
other then that you are good to go.
