Hey guys, I was just wondering if I should buy a GTX 970 off of eBay now. I have found several good offers for $170-$190 but don't want to get a card that was used for mining. Plus, should I get the 970? I have a dell with an intel i5 4440 and want to get the best bang for my buck. I have a 430W power supply and am willing to upgrade it if need be. My uncle said that I should get nothing less than a GTX 960. what are your thoughts.
