or you know.. playing gpu intensive games on high settings
not a waste
Well, again, two cards is overkill for that.
A single much lesser powered card can achieve that to FPS levels of 40-50 or so for a much better price. Since you are getting into a frame rate you can't even see by that time, its unnecessary for anything beyond self satisfaction.
Two cards? Really no point.
To me its like he is just looking for ways to apply the power. None of it will be very practical.
