howdy folks i'm having trouble with my vid card and i was told this is the place to come anyways this is my second build i'm running an asus mobo (not sure which model number sorry) with a 915 chipset a 2.66 pentium 4 prescott core and an x600 diamond vid card and i'm having trouble with the vid card. All right so it runs on the desktop fine but who cares about that as soon as I start up a game it is already lacking in performance over my brothers x300 (running on a worse mobo and a CELERON!!!) so you can see where my frustration is i can't figure out why on a game like counterstrike 1.6 and source and dod source my vid card just can't perform over my bro's x300 in fact it's performing a lot worse than my old geforce fx 5200 pci card not even pci express anyways if anyone could shed some light as to why it's doing this and how i could fix it i'd really appreciate it.
