Yeah, I'd wait as well for the DX10 cards, even if you can't afford Vista. You can still run them in DX9 mode under XP, and they're going to be much faster than current cards, even if they're just running DX9. Like ownage said, "The R600 is going to have 64 real pipes, 512-bit EXTERNAL and INTERNAL bus, and GDDR4 projected to run at 2000mhz+". That pretty much sums up the R600's beastliness, if it comes out to be affordable. You can always make the upgrade to Vista later to utilize the DX10.
