AquaMark3 performance is good, the PowerColor X800 GTO fairs quite well, even up to GeForce 6800GT levels! Impressive for a mainstream videocard.

Halo performance at 1024x768 is very good and the PowerColor X800 GTO videocard has no difficulty keeping up with the faster videocards. Gaming at 1600x1200 is a bit different... dedicated gamers would be better served by a more powerful GPU if they are determined to game at this resolution.
