A friend just purchased this card and is having some problems running it on a ASUS A7A with the ALI chipset AGP 4X...seems he's running the wrong resolution for his 17" sylvania monitor. He keeps losing his settings trying to go into higher resolutions and windows reverts back to it's default settings. He likes to play half life on line so I was wondering what is the best settings to use considering his resources? And does he have to tweak this card out at all for online gaming?
