I've been using the Skull=1 Skull=2 options with two instances of realtemp running for years now on my dual quad xeon setup. The only issue I've found is you can't launch the two instances of realtemp at once, most of the time one of them will be messed up, I don't recall the specifics. I use a batch file to launch one, wait, then launch the other. I'm also planning to pick up an 5960X soon. I'm just waiting a bit (for a change) to let everyone iron out all the kinks first. If there's anything I can do to help let me know.I actually wrote an 8 core version of RealTemp a few years ago. The guy on XtremeSystems that I wrote it for decided that he didn't like it because it was too wide. No kidding.
He thought for 8 cores maybe a redesign of RealTemp so it listed the temps in a table so it wasn't so big might be a better idea. Kind of like how Core Temp or CPUID HWMonitor do it. I don't have access to an 8 core CPU but in theory, either of those 2 programs should be able to handle the 5960X. If anyone has an 8 core CPU and wants to help me get RealTemp working, let me know and I will see if I can find my old code. A couple of minor updates might be enough.
