when you go to build your system prefer to have it built check out http://www.cyberpowerpc.com that is where I got mine done.  just go to the Intel or ATI system configurator.  A trick is since most all there systems use the same configurator if you want an intel system and they have one of the pre-built configurations with free shipping, use that then you can change every component to the way you want it.  I have been very happy with my setup.
