Single Nvidia 680m vs Dual 7970m

[kerplunk101]

Does anybody know what performance difference would be?

Once again, single Nvidia 680m vs Crossfire AMD 7970M.

This purely in terms of gaming. Both MMO's and FPS.

Thanks.

the HD 7970M CFX is obviously faster

It seems HD7970M become as fast as 680M when enduro drivers where fixed.
