Has anyone taken a look at GeekBench browser in the last couple of days? Go to Geekbench, select browser and enter 'iMac17,1 i7 32-bit' in the search box. Most of the performance figures are in the 15000 range (multicore) but in the last couple of days there have been a number in the 23000 range that claim to be for a 6 core 12 thread variant. It might be a Geekbench software error. Would someone really buy a 27 inch 5k iMac only to swap out the motherboard? Am I missing something obvious? Thoughts?
