Viper Lair posted a review on the MSI P35 Platinum Combo Motherboard

Overclocking the old fashioned way was actually very easy, despite the E6750's 333MHz FSB. With little effort, we were able to reach 490Mhz on air. Granted, we've had to increase the voltages to the max for CPU and chipset, but this was impressive considering we were using air cooling. I was able to squeeze an extra 4MHz out of the Gigabyte board, but given in the past I've had some issues with overclocking MSI boards, I was quite pleased with the results.
