Hello all, I have a gaming rig at the moment that I am looking to upgrade. Right now I have a GTX 650 1 Gb card in it which I'm looking for a major upgrade from. So on to my question which card would be better A radeon 7970 or a GTX 680? I have around $500-$600 to spend on a gpu and if you have a better suggestion then it is for sure welcome. My cpu if it matters is an I5-2500k and I normally play Battlefield 3, Skyrim, and will be playing Crysis 3. 1920 x 1080 resolution. Thanks in advance
