Why no cross-gen sli/xfire?

post #1 of 3
Thread Starter 
This is just asked out of curiosity but is there a valid reason why the sli of different cards is impossible? Is it a driver issue or a physical incompatibility issue? Seems like it would be a super appreciated feature and would make the companies more money. Srry if this is an idiotic question.

Difference in architecture, at times is already hard enough and enough development just to have SLI / CFX work semi-properly much less worry about SLI / CFX of different generations of cards thumb.gif
