OCC has published a new review on the Gigabyte EP-45 Extreme

Overall, I would have to say that the limited edition Gigabyte EP-45 Extreme is the best motherboard that I've ever used for overclocking. The BIOS was simple to navigate, and Gigabyte's Dual BIOS technology really gives the user some peace of mind knowing that if they screw one BIOS up, another BIOS is right there for them to use. The LED readout is an overclocker's dream, because it allows us to see where the issues are if the system isn't booting. For me, the memory was what was holding my overclocking back. I was able to obtain an FSB speed of 500MHz, which is extremely good, considering four threads of data are being sent through the Northbridge at 500MHz x 7 (3.5GHz). I don't think I've ever hit 500 on a motherboard due to some sort of bottleneck of the CPU or memory.
