Starting Rig Questions - What GPU and PSU

[twam]

Ill be doing work on it but nothing that required a good GPU. Just server monitoring and such all through a browser or HTTP/FTP/SSH client.
Maybe to watch a Movie or TV Show from time to time but i don't watch much of that anyways.
As for gaming the only thing it might ever run would be WoW but my 5450 can handle the game on highest setting, though again im not a crazy 8 hour a day wow player maybe just a couple times a week (I don't game a lot but when i do its usually a console... And no i didn't mean to have that sound like a beer commercial)

Now the waiting begins... Its killing me having to stare at my 5970 while i wait for my 850W PSU to arrive, Stuck with a 450W PSU and a 5450 for the time being.
