Hey Guys, I just need some advice in choosing the right graphics card, as I currently run with a GTX 550 ti it just isn't enough for the games that have recently come out, my most played games would consist of Battlefield 3/4, Arma 2/3, DayZ mod and Call of Duty Ghosts. I currently have a 600W thermaltake litepower and am considering buying a R9 280x graphics card, now would the 600W litepower be capable of running the R9 280X?
