Seems like the boys over at an EVGA have been busy fixing your concerns and adding to your delights.
May work even if you do not have EVGA cards!
Per Westsail and *Pyxey*
"RivaTuner would only over clock one card at startup for some reason with mixed class cards. I use this to otherclock the 9xx's and riva for the ati or 200xx. Also you DON'T need an evga card to use this utility as I don't own any. Tested on MSI and Tesla."

This program allows you to fine tune your EVGA graphics card for the maximum performance possible, with Core/Shader/Memory clock tuning, real time monitoring support including in-game, Logitech Keyboard LCD Display support, and compatibility with almost all EVGA graphics cards and some other companies too!

New skin format v1.2 gives new possibilities to skin developers and reduces skin file size and runtime skin engine memory footprint.
Reduced CPU usage for simultaneous GPU and PCB temperature readings, both sensors are being read in single pass now.
Added workaround for SLI mode switching related issues on ForceWare 190.xx series drivers. Now Precision is waiting for the end of SLI mode switching process before retrieving any data via NVIDIA driver API.
