Thanks donmarkoni. I'll put your name at the top my SLI tester's list.

Hopefully by early next week I can send something your way that you can test and compare to other GPU monitoring software. At the moment, when using SLI, RealTemp will sample each GPU temperature sensor, compare them, and report the highest temperature. My plan is to allow a user to check the temps of each GPU individually in a new window accessed by clicking on the GPU button. I would still stick with just a single GPU temp number in the system tray like it is now.

jcool: I can't remember if I mentioned this before but the RealTemp GT version should report the first 3 cores of each Quad on a Gainestown system. I'm thinking about adding the last two cores to the system tray as an option as well as displaying all 8 cores in the pop up menu over the first icon in the system tray. This way you could keep an eye on all 8 cores without the GUI having to get any more obese.

The RivaTuner plugin won't correctly identify some of your mystery CPUs but it should be able to read them all correctly.
