GeCube demo half passive Crossfire
ATI graphics partner GeCube have a decent presence at CeBit 2006, although they're a little reluctant to show off the IHV's most impressive products. X1900 XTX is limited to an unconnected board in a display case, and there seems to be little X1800 around either.What they have got is Crossfire using X1600 Pros, where one of the boards is actively cooled and one is passive. GeCube admit it's not likely to be a common configuration for an end user, but they wanted to put the demo box together to show it can be done with different SKUs and not just identical ones.
