One thing that I forgot to mention that is not very clear above - make sure your PSU has about 30 Amps (minimum) in the +12v total for the type hardware you are looking for. If it is multi-rail, make sure the rail with the vid card has at least 18 amps. That should be enough power to power this particular CPU and GPU with some breathing room. Anything less, and the system may not turn on.
-S
PS. I run 42 Amps on the +12 myself, but I also plan on adding a second vid card in the near future.
