I've just bought an XFX 7600GT 256MB AGP card and I'm seeing various artifacts in games. It's not overclocked and I've tried 3 different PSU's. It idles about 45c (25c above ambient) and max temp under load is 15-16c higher.
Supreme Commander has colour patches constantly appearing at random places all over the screen when Fidelity is set above Low, althoguh they don't appear when fully zoomed in for some reason. Does this problem indicate where the fault might be? I haven't managed to grab a screenshot showing the colour but this shows other artifacts I've seen in this game.

Company of Heroes - Opposing Front suffers from various glitches from time to time as well, which I think have all been cleared by alt-tabbing out and back again.





Those last two show a problem that I've also experienced in GRAW2.
So, is this card definately faulty. Is it the memory or something else? I just want to be certain before I start demanding a refund.
