Dedicated physx card

[julfo]

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
