The hardware is very good. I have 2 of the exact same Asus card, the main problems have been drivers not supporting features and graphic anomalies. My cards overclock very well too even in crossfire. (oops, I have the basic 5770 with egg shape cooler, not the CU core. but this means the hardware is even more capable given my cooler isnt as good as the CU core!) If it is his memory he will probably want to find why, unless he is happy to live with it downclocked.
