The GTX 295 has the performance of a GTX570 though, and the 570 gets 55.5 on that benchmark, so the 295 should do better than 55fps on medium settings.
He said he could get it cheaply. So let's consider that. BUT, (Big but hehe) that card guzzles power. It will probably cost more in the long term than a gtx 750 or R7-260x. I would go with the newer cards
