yes, you can connect 4 LCD's, if you like. And then you can switch to SLi mode (requires a reboot) and only use one display...and still have all four connected. It's quite nice, actually. 4-21 inch lcds......
I'd wait for the secodn revision of the chipset before making any SLi purchases...and at least 2nd revisions of the mobo's. But i guess someone has to take the plunge to get the bugs worked out right!
