If your thinking of overheating that caused artifacts, I believed its more of a GPU memory failure, than overheating. Went under artifact scanning and got nothing, but with OCCT memtest, i got tons of errors within minutes.
Unless you know that the heatsink is actually making good contact with the chips then you can't rule out overheating. You can see the GPU core temp, but you aren't seeing the temperature of the memory chips. I've pulled the heatsink from my card one time and I can't see how the pads were doing anything at all. The idea in underclocking your memory is that artifacts start showing up when you've pushed something too far. Your vram may infact be dying, but you might find them stable at a clock that is lower than stock. When overclocking you usually back off a little after you start seeing artifacts, so start reducing the memory clock in MSI Afterburner and stressing the memory. You might not have any luck, but it's worth a try IMO.
I don't think he meant to sell the card as working, but rather as a dying card. Someone might use it for parts, try to coax it back to life, or for a wall ornament. It's better to get a few bucks out of it rather than let it collect dust.
4670 < 8800GT. The best card you're going to find is an 8800GT
. It's a step down from your GTX 260, but it's not that bad of a card. It may be a little old, but it can still kick some ass. Other than that you might be able to find an 8800GTS/9800GTX/GTS 250 used.
