I had a GTX280 (for PhysX) along with my 2 5870s on a 1000w PSU yesterday. No problem

Might be a problem with 2 480s mind you

I still have to try the power hungry SLI 480 setup (should be here in the morning). Fingers crossed that it's a good experience
Problem is that people aren't making the connection between TDP and heat. Apparently some think that electricity just evaporates into pixie dust.

Anyway, again, 480 is a great card. If I didn't have my 5970s then I would look at SLI'ng a few of them on water--especially since they scale so well with an overclock.

I have tried that combo as well with no problem. I've since downgraded to a 9800 GT for Physx though because there was just no benefit to using a 280 instead.

My guess is that the 480s will be an entirely different problem. 2 x 480s is probably equivalent to 3 x 5870. Hope you'll check it out. If I'm gonna have to give up using a 3rd card for Physx with the 480s, then I'll probably stick with the 5870s.

Same - If they ship tonight (as they are supposed to), I'll know very soon

I'll be hard pressed to give up my 5870 CF config tbh. We'll see soon enough

Now that's what I call a gaming room. One rig with 5870 Crossfire and one with 480 SLI. I wish I had the cash to build a couple of rigs like that.

Meh, I wish it was still winter. Even if both of them sucked, I'd still have a warm apartment

I never have the heat on during the winter, and I live in NYC. My computers serve as excellent space heaters. Plus if I need impromptu cooling for my PCs, I just crack open the window and let the winter cold and wind do the trick.

My ATI machine is only one GPU though, I'd like to upgrade to a 4GB 5970 in the future but $1000 is too much to spend on a "secondary" gaming machine. Maybe when the ATI refresh comes.

Have you seen any benchmarks of a system running a GTX480 with a dedicated Physx card vs without?

I haven't. I would bet that processing is not the weak point of the 480 at 1920x1200 most of the time... rather its the fill rate and memory bandwidth (which aren't affected by the shader processors being used for Physx).

I'm assuming that a GTX 480 is a hell of a lot faster doing graphics and physx then my GTX 260 is, and I've already listed the "cons" for keeping my 260 as a dedicated Physx card (power consumption, cost, heat output, physical space, ventilation, having to mod my case...).

At best I may consider getting a GT240 some time as a PPU to go along with whatever card I end up getting, but I doubt I'll bother if I have a 480. I just don't see the 480 being significantly shader limited by current Physx games.

I wouldn't mind being proven wrong though. If anyone has a 480 and a 9800GT or a GT240 and a PSU strong enough to run them both, I'd like to see how the performance increases in games like Cryostasis and Metro 2033.
