Re: Three cards, two in SLi?
Why do I always find the answers to my questions after posting a thread?
From nVidias' site:
Can I add a 3rd graphics card in my 2-way SLI enabled PC to connect more monitors?
Yes, you can add an additional graphics card to your PC to connect two additional monitors. The additional graphics card must have a GPU that is different from your SLI GPUs and must be NVIDIA PhysX capable (GeForce 8 series and higher with at least 256MB of memory). For example, two GeForce GTX 2XX GPUs in SLI and a GeForce 9XXX GT is a supported configuration.
Anyone with this setup, or experience doing this let me know what problems if any you've experienced.
Re: Three cards, two in SLi?
You should have no problems I run 3 x 260 GTX and 1 9600 and have had 3 different monitors connected at one time. Main display (3D) on the SLI and 2 others on the 9600 IIRC. I know you can run 2 monitors off of SLI and 1 off of the 9600.
