Graphics lost after update to 10.9.3, nVidia GT 435m

[avin7000]

I had perfectly working Hackintosh on 10.9. However I had to update to 10.9.3 cos of Xcode Beta 6. I have taken back up of kexts from /S/L/E directory
 
Here is what I did:

• Downloaded 10.9.3 combo update  
• Installed it
• When I booted it started going to blank screen after Io Bluetooth Completed
• So I removed all graphics related kexts AppleIntelHD*, NVDA*, GeForce*
• Rebooted. Now I can boot into it 10.9.3, however no graphics. The resolution was at 1280x1024
• Restored kexts from back up, no luck, same error as step one. Removed them and rebooted again.
• Then I installed these kexts (I have also attached same kexts as attachment here) , now resolution is fixed at 1080p, however I find it quite slow. It takes time (in mili seconds perhaps) to draw the graphics on screen. Not sure how do I explain it better. It's just slow.

I load DSDT from /Extra/dsdt.aml (I have also attached this)
smbios.plist (located at /Extra):

Try to use smbios to iMac14,1

^I think it may work, however I followed the advice here pikeralpha.wordpress.com/2014/05/01/os-x-mavericks-10-9-3-build-13d55-seeded/ and edited the relevant kext to match my smbios.
