Recently I bought a gtx 560 that was said to give artifacts after 10mins of work, so I thought it was a heating problem and bought it. It has 1x 6pin connector on it, whereas in the card specefications says it should have 2x 6pin, so my question is, is this the possible reason for the artifacts or just the gpu is dying. Hadnt change the thermal pads and paste yet, will post later when done.
