Need help optimizing 5970 and 5780 rigs, back from retirement

[MajorMiner]

Howdy! Back from my sabbatical need some help making sure my mining rigs are up the snuff. Got the latest cgminer 2.10.5 with intensity at 9.

The 5970s are yielding ~700MHs and they are finicky when it comes to clocking up GPU and clocking down memory.

The 5780 is yielding ~370 at stock settings.

Any recommendations in terms of latest stable Catalyst drivers, improved cgminer settings or GPU and Memory tweaks would be appreciated!

Thank you all in advance!

I was able to achieve 800Mh/s with 5970 using BAMT
Cores overclocked, memory underclocked, max intensity.

Go through harware section, look for 5970, there is a guy with detailed setup and power consumption for each.
