Is it compatible? I have an i5 3750k and a 600w psu. The specs on the psu says it has an 8 pin pci-e connector with 2 removable pins. I currently have a gtx 550 ti oc'd to 1GHz. I can't get any more speed out of it without crashing. So will the 1060 fit my mobo? More importantly, is it supported? OS is Win 7 64bit.
