btw.
It seems that NV is going to steal some HD4890 sales in advance - with $169-179 GTX260-216.
a 260-216 is on par with the same priced 4870-1GB, why would it steal sales off of a better product?
The B2's were also used on the Quadro cards where they launched in september/october already. not seeing a uniform spread of all revisions on current boards (and the 295 issues) seem to suggest low yields.
