MAX # of GPU under windows?

post #1 of 10
Thread Starter 
I'm curious what the maximum number of GPUs is under Windows. Googled around, couldn't find anything...

I'm thinking of getting 6-8 GPUs going on a single mobo via dual GPU cards..

I know you have to dummy plug them or use a monitor, which I'll do.. Just need to know if there's a driver limitation

I thought it was only 4. I believe the number of Gpu's is limited by software right now. I know you could only have 2 5970's on a board because it was considered quad crossfire. Not sure about Nvidia or the newer cards.

It depends on the software, folding and video editing will use ALL video cores, but things like games use built in software from nvidia/ati which is limited to 4 GPU's

Its gonna be workstation software that can use up to 8 GPUs so I wanted to do four 5970's or 6990's

I'll give it a shot n see how it works out

Did you get it to work yet?
Please give some updates.

They should make an emulator that allows a computer to split the workload of any game into whatever number of GPUs are available, regardless of the game's coding.
