Here is my updated build. I didn't like that crossfire motherboard for the HD 4850 and this is a pretty good price for the 9800GTX (I might get another one soon, to run SLI). Also I replaced the Velocoraptor with the 2 hard drives to run in RAID O (is this a faster choice than the 10,000rpm of the raptor?) Let me know what you think..
