It's nice to be upgrading part by part but it takes a whole lot more of $$$!!
Imagine what a rig you could get with ~$1300 now
@ Shawnhill, if I were you, I woulg get a separate power supply and NOT use the one that comes with the case. Logysis is not a good brand for power supplies, I tell you by experience
Get yourself something like a Cooler Master, Thermaltake, Antec, Corsair, OCZ or Rosewill.
