http://www.bit-tech.net/feature/80/ the link shows one asus board fit to provide dual ati gpus. any card since the X300 will be compatible because of multiple GPU rendering technology invested in the cards since THEY WERE MADE, pity that ati hadn't realized the power they were holding. but its soon to come out in a month or two!
Sweet dude, I was worried they weren't going to announce that for awhile, gald to see ATI is jumping on the dual-video card wagon. So any PCI-E card from ATI, nice, two X800XL's should do pretty well together, saves about $200 compaired to nVidia's 6800GT's.
yea but i wonder how good the chip is against the nvidia sli, get ready for another vid card war haha tho ati is gonna be ahead since they mounted multiple gpu rendering chips in every card since the X300
