$800-900 Gaming Computer Build

Great build, but I changed your ram to a much more inexpensive one that will perform just as well. I also changed your power supply to one that is of much higher quality for the same price. With the money that I saved with the ram change, I put in a CPU cooler. An extra $10 from your original posted build, but I think the changes are very worth it.
