Seems like a bit of a waste as a dedicated PhysX card.

Plus we have no idea what kind of power draw it'd generate operating as a dedicated PhysX card.

Now - what 550W PSU? Some 550W PSUs can only manage a realistic 250-300W. Some can handle 650W. Which one do you have? Brand and model, please.

Now, the 8800 Ultra draws around 160W. The 8800GTS (512MB? 640MB? 320MB? 256MB? I'm guessing 512MB) draws around 100W. This is of course during normal gaming activities. Overclocking will draw more power.

The Q6600 at stock draws around 100W. The Q6600 overclocked can draw up to 180W.

The rest of the system is likely to draw 30-50W.

So you're looking at a minimum of 390W and a maximum of 470W draw.

Even a decent 550Wer would be operating at the high end of it's load capacity.

That PSU has a max of 432W on it's three +12V rails.

Even at the minimum of 390W, with ~375W of that being on the +12V rails, you're pushing it hard. 87% load. And the Cooler Master hasn't been independently tested by anyone with proper equipment.

It will probably work with all overclocks off, but the fan will likely scream loudly and it's possible you'll run into ripple/noise related instability.

I'd suggest a Corsair HX620.

I would think, seeing as it's a multi graphics card system, a high power single rail PSU would better suit, as the HX has 3. Silverstone OP750 would get my vote.
