The Inquirer has some interesting news about NVIDIA's upcoming ForceWare 90 drivers.
They heard these drivers will enable users to use more than just two GPUs or two graphics cards in SLI. There are even pictures out on the web that show motherboards that can handle four graphics cards!
Nvidia just released release 80 of its drivers and Nvidia usually releases a new driver every quarter, so I don’t think that you could expect to see this driver ready before late this year if not January 2006.
The biggest point is that Nvidia can do it and that this card will win some benchmarks for sure. We can only imagine how much power would such a system draw and Asus had an external PSU for this card. Will ATI follow this road? That remains to be seen..
