I saw the rumors the other day on the 650 and 660's.
I'm totally dissapointed about it.

I was expecting a 660ti, 768 shaders, and 256bit interface with 2-4gigs of ram.
Instead we get way more shaders, and less mem bandwith and such.

The reason I was expecting that exact config is because I would of liked it that way, half the wattage of the 680, but with more performance then a 580.
This sucks @ss...
I'm undecided if I should buy the 680 or wait it out another gen or 2.
I wanted a 100w card that kicks butt, but nooope...
Ohwell :\, ... I hope the rumors aren't accurate...
