PhysX Ageia Physics Accelerator

[DarkPacMan77]

I have a phenom II 550 dual core callisto that I unlocked to a quad core phenom II 3.1ghz. I applied an overclock to 3.6ghz and my processor is now a force to be reckoned with, but my 8800gt 512mb is starting to show its age.

On the 'Bay', an 8800gt 512mb can still fetch about $90-115 or so used, so I've just today purchased an HD4890 to replace my card (and eventually run Crossfire X).

I have a question though. I know Nvidia purchased Ageia and incorporates their physics engine into their GeForce graphics cards, but I don't know what ATi specifically incorporates to help process physics better. Would it be a worthwhile purchase to get an actual Ageia PhysX Accelerator card for PCI slot? Would that help or just take up extra wattage to run?

Don't bother. The video card will provide enough graphical power on its own.

Ok thank you. I figure it'd be surely more beneficial to just throw another 4890 in there if I needed extra power, but I was just wondering if I'd notice a marginal difference. Thanks.
