Unfortunately, there are no rebates over here.
I plan on playing at no more than 1280x1024 (and if I can get my hands on a good CRT even less as they do not have that stupid native resolution issue). But I like sims and racing games and lag just destroys the gameplay on those two, thus I would like some decent horsepower.
I too would want an 8800 GTS but that is $80 on top of the X1950XT, which is already 90 over the X1950Pro. That's a bit too much I reckon.
So the consensus seems to be for the X1950XT... interesting.
