Hello! So I recently decided to build myself a new gaming desktop (it'll probably be the last big upgrade for a while). And so i've allowed myself $1,500 dollars to build this computer. I would like it to be cross fired, When I have a new (relatively) power supply what is a 400W. I also have 8G of ram in current use. I also will be using my old hard drive (1T) but i might be swayed to purchase another, and or different ram (the current one is DDR3). So, I challenge the Tom's Hardware community to help me build a top notch gaming rig that will handle anything i throw at it for a price under (cannot be over $1,500 at all including shipping).
