Ok, tried a few times last night to get it working, no luck. Fresh windows install, remount gpu, switched one of the vga power supply connections, still freeze on black screen when trying to install drivers for gpu.
Moved gpu to second pci-e slot today, it doesn't freeze on black screen now, graphics get funky for a second then it finished driver update but I get windows error code 43 and it disables it. I don't have a bunch of extra parts that I can play flip-flop with to try and figure out which part is bad if one is, only thing I might be able to do is try and pull the gtx 680 (maybe ti don't remember) from my old pc and see if that one works...
Really not looking forward to having to deal with trying to RMA something especially since I've heard newegg are dicks about it these days.
