Hi, I want to build a new computer, with the help of my friend to put the parts together. I want this new computer to be able to play Diablo 3, BF3, Skyrim, SC2, WOW, SWTOR, and other games like those smoothly. Not on the highest settings just be able to run BF3 hopefully on medium. Although I want to try to keep the build under $600. Can anyone help me with a build. Thanks in advance.
