Hello friends , I am using sapphire vapor-x r9 270x ! I dont why i am feeling like this but i think i should have bought the r9 270 not the x version! is there really any difference ? I feel also laggy sometimes ! though i am using phenom 2 x4 955 processor but soon i will upgrade to i5 4590 ! should i swutch to nvidia for smoothly gameplay ? Gtx 970 is out there but is is a bit expensive . I will game ay 1080p
