I have a Powercolor Radeon HD7950 graphics card. When I open Firefox the images on the webpage and the browser itself appear all messed up. It doesn't seem to happen in games though, but I guess I haven't really played long enough for it to show. I'm pretty sure it's the graphics card because the same thing happend to my Nvidia Geforce 8800GT just before it died. Could anything else be causing this because I've got this card for less than a month now. The temps seem fine, idle is at 34 - 36 degrees celcius and in games it's 62 - 68 degrees celcius.
