300pts diff.. I suppose that's okay. Once I saw the proxycon fps start at 90, I was sure the score would have been even higher (because I was getting low 80s before), but I guess not!

I'm only at 2925mhz - I'll edge that to 3200, but I don't know if I'll be able to figure out the right combo of voltages.
