Just surfing extremetech.com and saw this article... Hey lorne you might be interested...    http://www.extremetech.com/article2/0,1558,1591812,00.asp  Using PCI express with 2 video cards on an array... Hmm... almost 2 times the power of the current cards.... I guess... But first we need to be able to max out the current ones!!! Then we can start using arrays...     I also am guessing that PCI express is going to take some time to come to AMD products because Intel is developing it.... They dont like to share.
