Apart from the improved cooler (and as the name suggests), the Power Edition of the MSI GTX570 features an improved 6+1 Phase PWM design which should translate to increased stability under maximum load thereby improving the overclocks possible. Couple this with the improved cooling design, multiple voltage tweaks courtesy of MSI's own fantastic Afterburner GPU overclocking utility and the MSI GTX570 Twin Frozr III Power Edition OC graphics card should turn it into an overclocking beast. Indeed MSI claim these improvements furnish the graphics card with up to a 22% overclock on a reference GTX570. Something we will be putting to the test later in the review.
