Hello.I wanted to upscale my mining rig, so I went in eBay and found 3 5970s for $200! But the seller says that one GPU on all 3 cards did not work properly. If I am not Using crossfire since I'm mining, would this be a problem?
If one GPU already isn't working, I would wonder how long before the other one craps out. I think you should be able to mine on one GPU per card, but I am not 100% sure. I would probably look for something else just because of my first point above.
