Slayer322, is your processor the Athlon X2 3800+ or the Athlon 64 3700+? Because the X2 3800+ isn't the Venice core, it's either the Toledo or Manchester. By the way, nice system, although I'm not too fond of ThermalTake's water-cooling systems...3/8" tubing doesn't cut it. I would rather pay more for 1/2" Tygon and get better results. Either way, I like the X1800 XT.
It's pretty nice, although I would rather go for the R580 series instead. The X1900 GT is my next card, pretty good specs for $300-ish.
