I have 85 dollars to buy a used graphics card in Ebay, so i found a Asus Strix gtx 950 2GB and a EVGA gtx 760 SC 4GB, i really want the 760 bcs is 11+ better than 950 and cheaper, so the problem is that my PSU just have a 6 pin connector, and 760 needs 6+8 pin, can i buy an adapter for the PSU? if yes put me Ebay links(No more than 3 dollars please).
