I am deciding between buying a gtx 460 and an antec neo eco 520w, or buying an hd 7770 and running it off my existing Dynex 400w psu. The hd 7770 would cost about $120. The gtx 460 + power supply would cost quite a bit more. Around $160. So here's the thing: I know simply buying the hd 7770 is cheaper, but I'm worried about using my old Dynex 400w with it. I feel it might be better to get a new psu, but if I do, I don't have much for the gpu. So.. Any ideas? Thanks guys
P.S. Again I'm not asking whether to buy solely a gtx 460 or a hd 7770, it's the power issue I want to know about.

Now that I think about it, I could try to catch the HD 7770 on a sale and that would take care of the problem, and I could get a PSU as well.
K I'll be sure to get a new psu for the hd 7770. Any suggestions?
The Antec VP-450 is a decent PSU, and only $39. For $40, you can get a 400W Neo Eco. They're both decent PSUs. The VP-450 isn't 80+, but don't be deceived; it is efficient enough (it might make Bronze), but is disqualified for not having active PFC.
AMD site recommends a 500 watt PSU, but any QUALITY 450 watt PSU would do. Like a Seasonic, Corsair, Antec.
The V2 Corsair Builders are not up to Corsair's past high standards. They review well, but have been found to use inferior Samxon capacitors that may not hold up.
