looks like unmature drivers to me. 8800GT in the same ballpark as what is essentially two 8800GTS. Once the SLI drivers are sorte,d this will kick the living sh** out of the 3870X2, who's catalyst Crossfire drivers work very well (180% in some cases of a single 3870).
Still think that a 8800GTS G92 is the best card money can buy... this is the one i want...
