Is this build any good? My budget is around $500, already have a 23" 1920x1080 monitor, have a keyboard and mouse, and a new copy of Windows 7. I will mostly be playing Minecraft, BF3 and 4(When it comes out), COD Black Ops and MW3, Trials Evolution, and all Need for Speed titles. Will this run AT LEAST Minecraft and NFS at high settings at a playable framerate? and could you tell me how it would run the other games listed? If it can't handle those games, could you make a build for me?
