I have just bought an XFX 7900GT with a 520MHz GPU off eBay. It works fine but I get nasty artefacts in games - big black or white strips. The nVidia utility tells me that the GPU temperature is fine, well below the slow-down threshold.
This is actually the second 7900GT I've bought - I wanted a fast-clocked one but accidentally bought a stock-clocked 470MHz one, and that works fine without artefacts (although it's obivously a little slower). This indicates that it's not a graphics driver problem (I'm running the 94.24 drivers).
Any idea what might be causing the problem? Is my XFX a faulty card?
Thanks
