Hello,

I am currently in the process of building my own custom CrossfireX system with two AMD Radeons. I do have an extra nVidia GTX GPU lying around, and an extra PCIe x16 slot on my motherboard. Will I be able to utilize all three cards if they are all on the same motherboard, even if they are different brands?

you can use the nvidia card as a physx card. Assuming it is one of the models capable of physx.

It's the geforce GTX 480, so it does have Physx. So as long as I get a power supply that can support all of those cards, I can run all of them?

You will need to use a community patch for the nvidia drivers for the software side of things to work. Now what model psu do you have?

If you try that, let me know how it works. Even if I just have to run the cards individually without any Crossfire, that's fine. I just want to know if it can be done

I've ran the GenL hack with crossfired 6950's with a physX card. It had no negative effects other than extra power draw and heat.

if you already had a gtx480, i assume you went with 2 x high end AMD cards. you will need a really beefy psu to use them all together. It would have been a good idea just to get a second gtx480.

Well I like the quality of ATI cards now days but that 480 is still a very decent. I hate to say it though but psu is holding you back like most.
