I just realized: I'm going to need a new PSU to go from 7800GT SLi to 8800GT SLi, right?

I was running a 510 watt PC Power and Cooling Turbo-Cool 510 with my 7800GT SLi/X2 3800+ system. The motherboard was fine with 20-pin ATX and these just happened to be 7800GT cards using standard Molex/AMP 4-pin power connectors due to the lower power requirements.

I replaced that nF4 board & AMD CPU with a Asus P5N32-E SLI Plus and a Q6600, using those same 7800GT cards as a holdover for the next gen DX10 cards (two 8800GTs are in the mail!).

After discussing it in these forums, I was advised to switch to my Antec Neo Power HE 550 PSU due to the lack of proper connectors on my PCP&C PSU and insistence that it would handle the SLi setup just fine.

Now that I am replacing the cards, somehow I doubt that a $40 PSU can handle it. 8800GTs are praised for not needing a second PEG power connector while the 7800GT was praised for being able to accept standard Molex/AMP 4-pin, so it's safe to assume that the power savings of the 8800GT over the GTS+ is not enough to bring it to 7800GT level! ;)

What do you guys suggest as a bare minimum for 8800GT SLi + QuadCore Q6600? Recommended? Things have changed a lot since PCP&C was the only trusted name... now there is actually competition.
