I've come across a 290x for 150 on craigslist. seller said hes owned it about a year maybe a little more and it got around 10-15 hours of playtime a week. I've been wanting an rx 470 but the longer I wait the more I'm willing to settle for something cheaper. so I'm asking you, is it worth it to buy it used for 150 and will it last me a while? like a year or a year and a half?
