nForce Professional Technology Overview
 

"Compared to what was previously offered for the professional market in
terms of the Opteron workstation and server side of things, the nForce
Professional is a vast improvement. While the performance is in question
until we see some professional level benchmark numbers, feature-wise
NVIDIA is putting a lot on the table."
