I have basically the same setup but with a different graphics card (GTX 650).
Issues I have run into.
-Safari can not play youtube video's before and after the flash player update (freezes/hangs machine).
-Sound sometimes crackles when playing videos through chrome on youtube (chrome youtube works).
-Bluetooth sometimes drops on reboot or during usage (using onboard bluetooth with both antennas attached which was stable on 10.8.2).
I got around the Safari bug by using chrome (I would like to use safari as it was supposed to be improved).
The audio crackling every now and again when watching youtube videos is almost a deal breaker and I kind of want to go back to ML.
Maybe I did something wrong in Multibeast.

Is it possible to roll back to the 10.8.4 audio from Mavericks as I saw a post in this long topic of a user rolling back from 10.8.5 audio to 10.8.4. If so, how would I go about doing that? Thanks in advance.
I fixed the imessenger issue with the FileNVRAM.dylib file but went poking around the imessenger settings and saw the account was not enabled. After that, I have not been able to get it working again.
EDIT iMessenger fix:
I followed the deleting plist and ethernet, reboot and adding ethernet back (plist regenerates) process in this youtube vid and it got my imessnger working. I left my FileNVRAM.dylib file there.

EDIt 2: Youtube on Safari seems to be working now and I think the sound is not crackling on Safari. I installed a lot of video players to increase the codecs I had. Not sure if that helped.
