pro : with all the negative review I have see I still want to chance it since I have be wait for this card since it be announce . Mine come with a boost of 1293 out of the box that I discover when benchmarking . well I fire up the Heaven benchmark and it crash right away ! I obtain the latest version of precision x and put the power target all the way up -lrb- 117 % for my card -rrb- . that not only take care of the crash at boost level 1293 , but I decide to try for higher . I be able to add +29 to my base clock of 1059 so I now have 1088 of base clock and a boost of 1323 ! I be able to clock my memory +600 without a problem under Heaven benchmark , but 3DMark 11 give artifact at that speed . the final stable artifact free speed be +510 for a final speed of 7028 -lrb- 1757 x 4 -rrb- ! yes , I be happy ! remember to adjust you target power all the way up . it only use the additional power when it need it -lrb- 3d gaming and benchmark -rrb- . my card be faster than any gtx 680 I have see ! con : some be have issue due to the boost clock be so high on some card . remember it may show up as 1137 in gpu-z , but that change when 3d happen . that be when I find out my GPU boost hit 1293 ! use the power target all the way up in precision x 3.02 !
