Honestly not sure, i didnt look at the individual scores. But i just installed the 169.21 drivers and score 18570 running my stable 24/7 3.6ghz
Futuremark - ORB - Result Analyzer
so i think it might be a driver issue. I'm going to reboot and do a few more tests at 3.8 and 4.0 and see if anything changes. Be back in a few with results.
edit 1) 19422 @3.8ghz and all the same settings. Starting to think the last batch of drivers were the problem.

Going to 4.0ghz and running again.
edit 2) 4ghz run, 1.525v, exact same settings as the first 2 runs, and lost points again. 17264
Futuremark - ORB - Result Analyzer So confused.
After looking at the results of the 3.8 and 4.0 runs, i lost points across the board.
Also before anyone asks, my cpu temps never went over 62C
