That depends on how you look at it.

If you run single card with physx on it, adding a second weak card will still give you a few extra FPS in most cases.
But adding a strong card to physx, will give you even more.

So it all depends on how much you want to pay per extra FPS

A gts250 paired with tri-sli 470s would add almost 15 extra FPS over running the physx on the tri-sli.
But use a GTX465 instead, and you will gain another 8 fps.

I'm not sure about the truth of that statement, i just watched an experiment from LinusTechTips and tying a gtx 580 with a weak PhysX card dropped the benchmark of mafia 2 to 30fps versus 50 fps with the gtx 580 alone, here's the video

Maybe when ATI will implement it as well.
Until than, its going to be a bit more scarce.

Why not just grab a second GTX 560 Ti for SLI?

My sig rig is my brother's computer that i'm on 99% of the time..What i'm talking about is a completely new rig (2500k,4gb ddr3, gtx 570) that is all my own and i will have soon. Also what website arethose charts from ? I've seen them around and really like to use those as what to look for in the performance of a gpu.

Don't even sweat it. A single GTX570 will handle most, if not all games (short of Metro2033) maxed out at 1080p anyway. PhysX or not. My 470 could, and a 570 is stronger.

Having a dedicated PhysX card is nice. But like its been said, if the PhysX card is too weak, it WILL actually hurt performance instead of helping it. If the PhysX card is too strong (on the other hand), it won't add anything but excess heat.

ahh ok, gotcha. Yeah I'd definitely go GTX 570 SLI then. It's powerful-enough to handle PhysX. The chart is from techpowerup.com. That's the style they use for showing benchmark results.

Well using the strongest card with the weakest, isn't really a normal use of physx

Also, I'm not sure about their test.
They get 4 extra FPS from using a 560 as dedicated over a single 580?
Seems more than odd to me.
