I'm glad you're enjoying the new MLAA :) Although I have a little bit of bad news.

I've found that apparently when using programs such as Sapphire Trixx or MSI Afterburner, the card will stay in 3D clocks/voltage at all times. Also, it appears that 2 important .dll files for 'unofficial overclocking' are no longer included in 12.4 (possibly 12.3 as well? I didn't discover this until doing an uninstall/driver sweep/12.4 reinstall and then seeing Sapphire Trixx no longer could see what version of CCC I was running nor would it allow me to overclock). You can download the .dll's and you'll regain OC functionality but you'll find you'll be stuck in 3D mode.

two .dll's found here: http://forums.guru3d.com/showthread.php?p=4270324

If you're not overclocking or just using CCC to overclock there doesn't appear to be any issues in this regard, it's just a little annoying since 840 core limit is a little low for me.

Luckily for me, I'm one of those nervous types who break out into a cold sweat at the mere mention of overclocking. :D

Just really amazed at the performance boost this has given me!

S!

I tested those 8.96(12.4 beta) ones and they seem to work very nicely too.

Well after some more extensive testing, it appears that the 12.4 beta drivers seem to have issues with powerplay overall, even when not doing 'unofficial' overclocking (oc'ing above CCC limits) the card may bounce between 3D/2D clocks when it should stay in 2D and it may stay in 3D mode for extended periods of time. This is more an inconvenience than anything, but I figure I should report my findings here.

Edit: It appears that even though I had Sapphire Trixx set to not apply clock settings anymore, just having it running seemed to be causing my powerplay issues. It must be related to the fact that those 2 .dlls are no longer included in the 12.4 library and they must be what the overclocking software is using to interface with the card and with the changes in powerplay it must be causing a conflict.

Edit #2: Well after some more testing, it appears that once you enter a 3D application and leave, powerplay will kind of work, sometimes it's a little slow in downclocking, although mine doesn't appear to lower voltage if you're using 'unofficial overclocking'.
