PhysX help needed!

[Un4given01]

Alright, i was reading this article about physix: http://www.guru3d.com/article/physx-by-nvidia-review/3

For my setup, i'm doing

Multi-GPU mode - GPU1 renders Graphics and GPU2 renders PhysX.

I have a Galaxy GTX 460 as my main GPU, and my eVGA 8800 GTX as my PhysX processor.

In the article it says the following:
"Now there's a thing you will need to be aware of in the Multi GPU mode, it's actually a Vista limitation but a second monitor must be attached to enable PhysX running on the second GeForce GPU. You must extend your Windows Vista desktop onto that monitor.

To bypass that issue, most monitors have a standard VGA and a DVI connector, right? Just use both. This limitation is related to the Windows Vista display driver model (WDDM). This limitation does not exist in Windows XP. In NVIDIA's upcoming drivers, they will be offering a workaround to improve the experience for Windows Vista users. "

Does this still exist in Windows 7? Do i still need to do this? Currently i have my monitor hooked up via HDMI to the 460.

It's not an issue if i have to do it, because i have spare DVI cables laying around, but seeing this article was written in 2008, i just wanted to know if i need to do it or not.

Thanks for the help in advance!​

Does anyone know if this is still an issue or not?

I don't think that's still a problem considering the article is from 2008. Also, are you actually playing any of the few games that support hardware PhysX?

I don't think this is an issue anymore because I ran 2 X 9800 GT in SLI along with a GT 240 dedicated to PhysX last fall with the 252.XX - 256.XX series of drivers with Batman:AA and I could definitely tell the difference when PhysX was enabled for Batman's cape and the rustle of the papers on the ground in Arkham Asylum.
