Well, you were partially right. I didn't modify the benchmark, but it appears as though when I reset my BIOS to stock yesterday while having my prior overclock values in Clover's config.plist it caused a mismatch between internal core clock and what OSX what expecting, results=inflated benchmark scores for CPU & GPU, with no real world performance gains (actually everything running slower, even video which gives a FPS boost cause seconds last longer allowing more frames, but it can be hard to
see difference)

Since I have no interest in cheating benchmarks, I would have to say all those benches from yesterday are invalid. 7970 still kills it without cheating
