for 50$ used what can i expect from this card? i have an r7 250 ddr3 2gb and haven't been playing many games that came out on pc from 2015. i have a resolution of 1600×900 with an i5 2320 sandy bridge 6gb of ram and 450w coolermaster. is it worth buying this card to play games like overwatch'witcher3, battlefield one all those popular titles?
