Just took delivery of a 1730 (T8300_single 8700 gpu) with the new A09 BIOS. I do not buy that new BIOS has slowed clock speeds.
3dmark06 produced same results (4973 vs 4980) whether using new A09 BIOS or former A08 BIOS.
New BIOS seems to improve HDD performance.
I enabled caching under___ Device Mgr-> Disk Drives->Policies->Optimize performance->Enable write caching on the disk___and time to rip a coml DVD using AnyDVD and to compress using Nero Recode 2__dropped by 50%! 15 min vs 30 min for each operation!
Not sure how much of this performance improvement is due to (a) A09 BIOS and (b) enabling write caching_which previously was greyed out.

In short, fix the problem until the computer's off-warranty.
