B1 has now been extended to Q3...
295w, B1, 512sp @ 725mhz (Rumored Stock GTX485)
275w, A3, 480sp @ 725mhz +1050 mhz ddr5 (Overclocked GTX480)
250w, A3, 480sp @ 700mhz +950 mhz ddr5 (Stock GTX480)
Standby power consumption is currently GTX480 still have questions, NV is seeking the release of new drivers as soon as possible to correct bug.
Seeing as how this is now going to be a B revision chip, it makes much more sense that this will be called GTX485.
