ownage said:that i doubt, maybe a new revision for the 8800GTX, maybe GDDR4 implementation, but i doubt they will release the 8900GTX 4-5 months after they release the 8800GTX. But i know they will not retrace everything to support a 512-bit external bus, doing so will require a new chip and a new design. Nvidia is going to stick with their 384-bit external bus.
EDIT: I was quoting allenn812.
Oops, i ment a revision. But you never know what nvidia will do to stay on top!
