NVIDIA GTX 650 Support broken in OS X 10.9.3 - be wary of updating from 10.9.2

Hi guys,

Used to be part of the "Hackintosh" community a few years back, but been away for a while so bare with my shortcomings

To use NVIDIA GTX 650 in 10.9.3, remember to backup your kexts.
I'm not sure *which* is needed, but I restored /System/Library/Extensions/GeForce*.kext along with NVDANV50HalTesla.kext, NVDAResman.kext.

I haven't figured out what changed, or which file/edit was strictly needed, but I'll report back when I do.

So, enjoy the 10.9.3 update with GTX 650

Cheers

EDIT: After checking GeForce*.kext and NVDA*.kext, and comparing between 10.9.2 and 10.9.3, this is the only vital change I've found so far:
/NVDAStartup.kext/Contents/Info.plist
+ <key>NVDARequiredOS</key>
+ <string>13D65</string>

Apart from that, it's mostly code signatures and version bumps.

What broke?
What happened if you don't replace to the old kext?

13d65 = 10.9.3
