Power Supply Recommendation for a 8800GT 1GB?

Question

Okay, so I've had this card for a while now and it is working fine. Now, I know that the 1GB version is only 10-15% better then the regular 8800gt, but I still think I'm not getting the most out of it. Should I be upgrading my power supply?

My Specs:

Gateway GM5664

400wt Power Supply (stock)

2.3 Quad

3gb RAM

Vista 32bit

Any insight is appreciated.

Not unless it's overheating.  Switching supplies will either work or they won't, you won't get low voltage if you overload them.  (They'll shut down.)
