Just want to give a "heads-up" to everyone going for recent update to 10.9.2
I performed the update on 2012 12-core MacPro and got a pretty serious issue with ATI Radeon HD 5770 card. It has two "30 non-Apple OLED DVI 2560x1440 displays plugged in. #1 is connected directly to DVI port, #2 has to go thru Apple MDP to Dual channel DVI adapter (big one with USB power). When rebooted for an upgrade procedure it died with a gray screen. The startup Apple logo appeared on #2 then the display went to standby and #1 showed gray screen. I tried safe boot - no luck. NVRAM (PRAM) reset lets me log in once with the same startup display "switch", but #2 never comes on again and it's resolutions list and arrangement in System Preferences is empty. It's also pretty obvious to see video memory errors on top portion of the screen, odd Safari pages display, scrolling may cause random lines to pop...
Cables, displays, adapter - checked - no problems with other Macs.
After contacting Apple support and reporting an issue (awaiting further response) and successfully booting the machine from the different drive with older OSX I assume this to be an update software issue.
If you have somewhat of the same display configuration - PROCEED WITH CAUTION!
Be sure to have a backup and a spare time to waste...
Hope that saves someone's day.
