Also, BFG, EVGA, and XFX (I think XFX) have lifetime warranties on their cards. If something as little as the fan making noise/dying = new video card. But EVGA and more recently BFG require you to register on their website to get the lifetime warranty.
IMO, the lifetime warranty is well worth it. I'd rather play $30+ more for the same card if the more expensive manufacturer offered the lifetime warranty.
