Very cool, will look forward to hearing about your experiments. Quick update for me:

- I disabled "Cool and Quiet" under for my CPU in the bios, as suggested by a user on this thread: https://litecointalk.org/index.php?topic=14951.new;topicseen#new, but it didn't really change performance.
- I switched to a different mining pool, Shiftcoin for a day and my performance was somewhat dramatically better, at least in terms of hashrate. All of my cards enjoyed a 10+ Kh jump, was getting 715,720,740,710!

So it seems that the type of coin you are mining and/or pool you are participating in can also sway these results. When you guys are testing, do you mine just one coin, or?
