With only a single 4870 in the system and looking at budget then the OCZ stealthstream 600w. If you want to crossfire in the future then look at a corsair or PC Power and Cooling 750w

would the pc power & cooling 750w quad be able to handle two gtx 280s?

+1 on the Corsair 620w, thats the way to go.

Jayn, your talking 2 of the latest cards out there. im running a 800w kingwin and its flawless. you might have to jump up a notch from me to a 1T
