<< all the geforce3's that have been released have been almost identical in terms of memory/core settings, and performance. youre probably referring to (im assuming) what will be the geforce3 ultras, which have not been released yet. >>
I think he's aware that all current GF3's are clocked the same. I believe he's merely inquiring upon any GF3 cards that are utilizing RAM that is rated better then 3.8ns
I don't know of any GF3 cards that have RAM rated any faster then that. All the GF3 cards I'm aware of use memory that is either 4ns or 3.8ns rated.
