Hey.

I see lots of people talking about hardware accelerated Physx. I have a 7970. "Why amd and not nvidia?", you ask? A) Because I prefer AMD in general. B) because the 7970 overclocks like a beast when you get +1200MHz, and despite popular opininon, when you take the 7970 to the max it blows the 670 out of the water in almost every area (except power consumption, granted) and can even trade blows with the 680. Oh, and C) It was cheaper for me to get a 7970.

But that's besides the point. I want cool flashy physX stuff. So, I need a dedicated physX card. Can someone suggest a cheap (Pref. under £75) but adequate card to run just physX on?

Cheers

What games are you playing for this? PS2 isn't 100% confirmed to be doing GPU PhysX, so don't waste money one on for just this game.

Well, it was only gonna be for PS2 :P But I might wait and see until beta/release whether I need one or not. Cheers anyway :)

Didn't they stop making the dedicated PhysX cards? Would getting one of them even be useful at this point, I mean driver and game support wise.

And running an nvidia gpu in tandem with an ati.. not entirely sure if that would have any effect either, or even work to begin with :D

You can run a nVidia card as a physX accelerator, Otherwise, yeah there aren't dedicated cards anymore.

So you can actually use an nvidia gpu purely as a PhysX processor, with a completely separate card being the "actual" gpu of the system?

Yes but not officially with an AMD card (Nvidia don't want you doing it)

NVidia bought out the company that was making those, and that technology is now incorporated into NVidia cards.

They took the block off ages ago

I thought that was just a "bug" (http://physxinfo.com/news/3117/release-the-hybrids-nvidia-reconsiders-ati-nv-physx-setups/) in some beta drivers a year or 2 ago, the WHQL driver closed it. Nvidia really don't like people doing this, they even coded into one of their drivers an invert gravity timebomb (http://www.geeks3d.com/20100422/hybrid-physx-patch-1-03-with-reverse-gravity-timebomb-fix/) when an AMD card is detected.

Also the guy developing the hybrid physX patch has frozen development, so the latest Nvidia drivers don't work Hybrid PhysX

This is what I was planning to do.
