What do you think the most power hungry NVIDIA GPU I can run with this PSU is?

In acme's chair.
I have a system with the following (or rather I will once I have pieced it together out of parts):

Phenom II 955BE w' CNPS10X Quiet
Gigabyte GA-78LMT-USB3
4GB Patriot Sector 5 1333MHz
500GB Samsung Spinpoint
OCZ CoreXstream 500W

What do you think is the most power hungry NVIDIA graphics card I will be able to run safely at 100% load 24/7?

It has to be an NVIDIA card as the machine will be used for Folding@Home.
The kind of cards I would consider:

GTX460 1GB
GTX470
GTX560
GTX560TI

It has 444W and a combined 45A over the two +12v rails.

It has one 6pin and one 8pin PCI-E connector.

Have you considered AMD, if you don't really need the cuda or physics support you will be able to get more graphics power for your watts from AMD.

Yeah, should run the 460/ 560. I think the TI will work too. I have the PSU :)

Its a good PSU for the money :) My only gripe is the high pitched 'coil whine like' noise it makes sometimes. Have you noticed yours making any such noise?

The TI would probably be fine yeah, but i'm thinking that i'll get a 560 so I have a fair amount of headroom bearing in mind that it will be left on 24/7 at 100% load. But if a 560TI comes along for the right price, then I will probably go for it.

A 470 would run fine, bit cheaper too as they can be had for 50-60 quid. Great clocking cards, though a bit hot and loud.

I would preferably be looking for a twin fan card like a golden sample though because of the heat and noise.

Wouldn't it be ill-advised to run a 470 on a system with a cheap(ish) 500W (444W) PSU flat out alongside a 955BE 24/7?
 
The ocz youve mentioned in your op should be fine with a single 470. I ran two at 750mhz, (stock speed of 630 mhz) on an i7 920 @4.2ghz. Total power draw at the wall was 630w in game. You might be able to snap up something like an msi twin frozr, or a gigabyte 470 soc. Theese have great coolers, and the soc card uses a bit less power than a reference 470.
 
I ended up getting a GTX460 XLR8 :)

I was looking for a 470 to begin with, but this is doing the trick :D

Cheers for the help :p
