Will ATI physics require crossfire, or just two PCI-Express slots?

[eatmuchpie]

I'm currently speccing a new conroe system, and I have a plan

I'm going to buy the Asus P5B Deluxe which uses the P965 chipset (so there is no crossfire or SLI), however, it does have two PCI-Express slots. Will this be enough to run a graphics card as a graphics card, and a second card for physics?

I know that ATI physics is about a year off, but I'm trying to work out which board I should get.

Cheers!

There is no reason it should need Crossfire, but unfortunately that doesn't mean it won't need Crossfire if ATI want it to.

The Inquier seems to think that ATI want any GPU to work as a GP-GPU, provided you have another card handling the graphics. I doubt ATI will make crossfire a requirement for physics, because they'll price themselves out of the market.

Whether GPUs are capable of substantial physics calculations has yet to be proven.
