I currently have a fxf HD4650 single card on an old Pentium 4 single core 32bit board, and I'm upgrading to a AMD 965 CPU on a MSI 790FX-GD70 Motherboard. I don't want to discard the old card but I'm getting two HD4850 intended for crossfire. I want to use the 4650 as a physics card independent of the crossfire system. I found a description of this on the ATI website and I was hoping someone could explain how I could make this work with this hardware.
Thanx
Scott

I don't think that many games support a separate ATI physics card. Many games support physiX which is an Nvidia hardware solution.

I'm not sure how it works I saw a three year old description of it on the ati website. I think it was develped prior to quad crossfire.

i think that thing is pretty much dead already. and if i'm not mistaken you can only use X1000 series card as dedicated physics card

Those were the cards used in the discription. I have a much bigger problem now. I'm still trying to learn this I'm in the middle of my first build and all the parts are comming in. I've got the video cards now hd4890 I've got two for crossfire and I hooked one up into my old system a pentium 4 board. The boards from a gateway 506gr. I hooked up the card to get a taste of what I could look forward to but I think It fried the board. You wouldn't happen to know much about that card would ya?

back then ATI want to accelerate HAVOK with their GPU but in the idea typically dead when Intel owned HAVOK. (i'm not really sure how things going on back then so correct me if i'm wrong). Recently ATI announced that they are going to use BULLET physics engine to work on with.

Right now some people with ATI card using nvidia cards as dedicated physic card because they want to enable nvidia PhysX in game (game with PhysX support). but is more because of those game are built based on nvidia PhysX technology and PhysX run only on nvidia GPU.
