I am looking to up-grade my computer for a few of the new games that are coming out. I will be needing 8gb more of RAM, and new Mother Board, and a new GPU and CPU. I am trying to only spend $500 but would be willing to spend a little more if it would make a big enough difference. I have a 700 watt power supply and im not looking to over clock. I am also an AMD fan boy but am open to other options.
