after purchase and install this in my rig , it have outperform all my expectation . Run SWTOR on max setting beautifully . play game like Crysis 2 , Dead Space 2 , Far Cry have all be flawless . battlefield 3 be almost all on max setting . mw3 max out . wow play fantastic but its not a GPU heavy game but still make it look very nice . get a strong 7.8 Windows score . install afterburner and have it now tune and stable at over 1000mhz . most of it be do without any voltage tweak whatsoever . I think it be stable at 1040 with no voltage as I stress test it with Crysis and Crysis 2 . after 3-4 hour on Crysis it show sign of artifact . I back the clock down to 1020 and its be stable since then . after I voltage adjust it , I could maintain 1040 with no issue . have not go higher as it work great for the game I play . great card with enormous OC potential . stay cool even at OC would spec . Heatsinks and the copper pipe dissipate the heat very well .
