This card overheats and artifacts up on me after awhile, and there are stories of it happening to other people.
Don't get me wrong, when it's working it's great; Oblivion 8xAA + HDR + all grafix sliders maxed = avg 38 fps, and I was able to play Cell Factor at max grafix /w motion blur.. 7800 would crap out if it tried to do motion blur..
But all that is worth NOTHING when the card jams up randomly. I'm going have to return this card, and wait for a better batch. Being early adopter can suck sometimes.
