I've had no problems at all running cat 14.12 drivers for my 270X, but thought that I'd change to 14.9 and see what the extra PPD was. Well they are definitely quicker. On P10466 I got a good 10% increase, and on P13001 it was a 15% increase. Only problem is that I also had 4 driver crashes/restarts in a little over 3 hours, which required a reboot to get the GPU folding again. So 1 sunny morning wasted and now back on 14.12
