Hi, I recently got a sabertooth z87 mobo and a i5 4670k cpu. When I got it all together and started running benchmarks it started showing major screen artifacts until eventual crash. I reseated the card and it worked fine for ~24 hours, then the problem came back while in firefox. Reseated the card again but blew out the pcie slot and gpu with air first and again, worked for about 24 hours before crapping out. I suspected the gpu so I put it in another system and it has been working fine. Would this be a problem with my motherboard or cpu? Maybe a setting in the bios that is causing it? The gpu is a msi cyclone r6850
