Yeah, i did read the information yesteday too:
384bit bus @ 5-6 GHz = 240-288 GB/s
Compared with the 180GB/s of my GTX285 SSC, after 3-4 years, it's a 33-60% increase in bandwidth.
Prolly i will skip this card aswell.
Maybe the non Tesla/Quadro version of the card will feat the 512bit bus without ECC support.
That is my last hope.
