Overclocking performance on this card
is impressive! some rumours over the net report that it can touch the
toes of the HD5870. 30% OC on stock voltage.
Our conclusion:
Based on all these reviews we've selected, the Radeon HD 5770 seems to be a great performing video card with its powerful GPU running @ 800Mhz and 800 unified shaders units seems to get a good performance/price result, and if you are seeking a powerful one go ahead to the Nvidia GTX 275, for those who already have a HD 4850 and want to upgrade to the HD 5770 we advise to move up to the next generation and you will be satisfied with this last one.
