Ok, so i've had to RMA 2 graphics card, so in the waiting time of the first RMA i used my CPU Graphics *I7-3770 - HD Graphics 4000* and it seemed to run games fairly well at near-high settings. I recently RMA'd another card *Being the 2nd RMA* and now whenever i play a game on the CPU Graphics, i have to turn the settings to all low in order to play, and it even still has slight lag. The temperatures on the CPU are 32-35c idle and around 40-50c under load. Everything in my build is fairly new, except for maybe the PSU, but it has seemed to work fine without any flaws (Who knows, maybe it's that causing all of the RMA's and problems). The graphics cards were EVGA 660 SC.
