Hmm. Sorry, my notes seem to be wrong (or, given this market, quite possibly just out of date). I thought the "desktop" version was based on something else (82751, I would have guessed). >> They also have different bus interfaces -- which >> could be a sustantial speed advantage for the server version under >> high load. >> > > Again the PB clearly states both cards are PCI Express 1x... Just look > at the photo in the PB... The cards are identical! I still think there's a difference there, though; the "server" version seems to be 4x.
