Just a heads-up for any Joker owners having the same clock fluctuation issue - I flashed my card from the 031 bios to the 028 (from the link in the OP) and it worked a treat. Clocks/GPU usage are now constant as you would expect.
EDIT: I think all the 028 bios really does is allow you to turn off Powerplay. It still operates with fluctuating clocks with Powerplay enabled. I did a couple of tests in Unigine Valley and with Powerplay enabled (fluctuating clocks) I got 45.5 average FPS, and with Poerplay disabled (stable clocks) it was 49.7. Both tests were Overclocked to 1165.Edited by Vinegar Joe - 4/25/13 at 12:25pm
