just found this and thought it was quite interesting. There will be a MSI P55 Motherboard with a Hydra Chip by Lucid, which is supposed to be able to bring Multi-GPU systems to 100% scalability.
Looks like the Hydra chip will let GPUs render not only parts of the frame as it is now, but uses Multisystems as one GPU and lets every gpu render different objects of the frame.
And even ATI and NVIDIA are supposed to work well together.

If this really works I might get my first MultiGpuSystem
