Hello everyone. I have 2 questions i could use your help answering. i am considering upgrading my asus 460gtx to one of the fancy 680's that just came out. I am addicted to Bf3 and am finding that on some maps my little card cant keep up even tho i have it clocked at 850/3680. I game at 1920/1080. am i gonna see a hugh difference in framerate? i also am running an older setup which is Phenom 2 940 which i have overclocked to 3.4ghz on a gigabyte 790 board. i have a Cousair 550 watt psu, is this big enough to run a 680gtx. any comments or suggestions are welcome.
