Hello, Im looking for a budget gaming mother board, hopefully around 79.99$. I need it to be DDR3 compatible, run Win7, and go with my AMD Phenom II x4. I dont need any on-board graphics cards. I'm not too sure what the difference between Atx and mAtx is. I want it to be long lasting, and pretty much the best mobo i could get at this price-range. Thanks.
