Nice John.
I'm thinking this setup could be somewhat decent on subzero, got a new high in CPU test 1 for Vantage, 3913 steps @ 215x21, Wprime got a 5.663s @ 215x21, Geekbench is I believe 11.8k, 06 at easy clocks on the GPU (800 core/1240 RAM) was near 29k.
Vantage is a tough one though, really need a good OCer for it, around 4.7-4.8 benchable would be nice. I think an E5640 would do well, or a W3565/W3540.. But anyways yeah, not sure what to think of this 930.
