SuperPi is just incredibly single-threaded, so having a higher score doesn't mean much. BUT, if single-core frequency is what we are going for, then it could be included.
SuperPi just doesn't do much for me. It was far cooler back when single and dual-cores were king, but with the advent of Quad-Cores, it's lost it's appeal. For example, a 3.5GHz OC'd E6600 would beat out a 3.0GHz QX9650, despite them being on an entirely different level, and that's what I find odd.
If you all think we should include it... then we can. I do think it should be the 32Mil test only though... the others complete far too quick.
