I will agree about the 54, if you could find another comp in the same price range that sports a 7200RPM HD then you might give that a try, otherwise look for an external for the vid files as JohnBoy said. Also, Gateway has a rig out now with DDR3 ram which is slightly more stable and faster. If the price is similar, you might check it out.
Other than those two things, the rig looks good, and trust me, you will love that nvidia card.
