Hi, I don't believe that it's been posted on the forum, but my understanding from the guys at bitcoinza is that bitfury now rates the chips at 3GH/s per chip. Bitfurystrikesback have also updated the info on their website to state "Demonstrated performance 3 GH/sec @ ~0.85W/Ghps" for these chips and, as we know, these guys are very close to bitfury. Bitcoinza are expecting to have prototypes soon and I'll post news about their test results as soon as I hear something. Cscape's S-board prototype achieved 2.5GH/s per chip with sub-optimal cooling, so pushing the cards further seems quite plausible (cscape even said in his S-board post that the cards should be able to achieve "probably more with better cooling")
