There seems to be a few "sleep bugs" Mine is just the annoying disconnect on monitor sleep, and reconnect on wakeup. It takes freaking forever, and makes a bunch of racket with the bing-bong noises. From a technical viewpoint, the Virtual desktop is deactivating on sleep, wihch its not supposed to. It should just activate DPMS to turn off the signal, and leave the desktop activated. It also wreaks havoc on eyfinity. 13.12 was the last driver it worked correctly on. But yeah, its still there.
