Alright, so i have built my main gaming rig, 7970's crossfired, i5 3570k, ssd , 16gig ram etc etc, but i have no idea on what to do with a budget AMD rig. Main use would be for movies and some light gaming. I would still like to be able to play bf3 at say 40 fps on medium settings. I have no idea which AMD board to get, or which cpu crossfires with which amd gpu. Or if the onboard graphics would be enough to achieve this. Maximum gpu i would want to get is the 7770 to crossfire with onboard. Budget i would like to be under $500. I am not against using a intel i3 or something but my understanding is AMD on board graphics are better and can be crossfired with a lower card for better performance.
