Yesterday, just for kicks, I changed the <count> setting on my 980X+7970 to <count>.083</count> to try and get 12 GPU WUs going.

So far, 24 hours later, it seems to be doing nicely. It went from 8 in ~3.5 minutes to 12 in ~4.5 minutes.

10/28/2012 0:009:16:46:05 978,709 4,128 (running 12)
10/27/2012 0:007:19:44:55 906,234 3,887 (running 8)

Some of that gain is from PVs catching up, but it seems to make a material difference.

Anyone else have a hex core trying this?
