There is not much they can chop off after the 8800GTS 320MB, tbh I just see this coming down in price to fill any gap.
Doesn't it have, like, 96 shaders? Lots left to disable!
Or they could use slower memory, too...
The monster that is the G80 die can't be cheap to fab, and I don't expect them to find any extra yeald over what they have already done with the GTS....
Memory speed, possibley they could reduce the costs a little, but not going to make much of an impact are they tbh, nah I think that the GTS320 will be the lowest 8800 (apart from mobile) we will see...
If there are chips which are either damaged or won't run at the rated speeds... then what does nV do with those ones?
