OCC has published a review on the MSI HD R5770 Hawk
Now, after talking up the overclocking potential of the military class components and great cooling capabilities of the MSI HD R5770 Hawk, did it live up to it's overclocking hype? The answer to that question is a resounding, yes! During overclocking the Hawk's GPU core maxed out at 1025Mhz, which is roughly a 17% overclock and the memory was extremely overclockable as well, reaching a final frequency of 1410MHz before running into any stability issues. These clocks will make this card an absolute value to the overclocking community, but the MSI Hawk isn't done yet.MSI HD R5770 Hawk Review
