I recently bought an EVGA GTX 970 SSC for $70 from a friend of mine who claims it's been mining for about a month. I've tested it in Furmark at 1080p with 8x MSAA and it seems to be stable at 58-65 fps. The temps were high at about a 91°C average in all of my tests. Both fans work silently under a normal gaming load and I didn't immediately notice any discoloration on the PCB. It seems a little too good to be true at this price, given that this card has been running for 730+ hrs likely at full continuous power. Does a month of mining do all that much to a graphics card? Am I just stressing over nothing, and these cards are more durable than I'm giving them credit for? Edit: Thank you to everyone who replied! The thermal paste on this card had either gone completely soupy after it's use, or it was just cheapie paste. After removing the heatsink, I saw that there was little to no paste anywhere close to the actual GPU die, which would explain the 91° temps I was seeing while running Furmark. After carefully applying some Arctic MX-4 paste to the GPU, my temps dropped SIGNIFICANTLY. Around a 30°-40° drop during synthetic benchmarks. This seriously boosted performance in synthetic benchmarks, as well as normal gaming loads. Around a 10fps difference in Furmark at 1080p to about 68-70fps, and somewhere in the same ballpark on the games I play. I've never repasted a graphics card before, so I appreciate everyone pointing me in that direction. I believe we've breathed new life into this card, and I'm excited to get into some newer titles with it!
