GeForce 8800 Ultra With 0.8ns GDDR3

Heard from anonymous source, GeForce 8800 Ultra will be annouced at 5/1, and you can buy it at 5/15. This monster will use 0.8ns GDDR3 video ram from samsung. Core and ram speed have not been decided yet, anything else should be same as GeForce 8800 GTX. Does this mean GeForce 8800 Ultra's ram speed up to 2.4GHz or 2.5GHz? Wait and see.
