Crash/Critical error in and around Dalaran

Greetings, I'm crashing very frequently while in and around Dalaran, I end up with a critical-error message I also suffer low fps in that area even though my PC handles retail at Ultra with constant 60 fps, I am playing on Lordaeron and using the new client.

My rig:
Nvidia GTX 680, i5 3570k, Windows 10 pro 64-bit

Yeah, i got some Fatal erruors too. But i ran out of Dalaran. also im Playing at work, from External hard drive.

1. Remove WoD models by using this Guide http://forum.warmane.com/showthread....the-old-client
Or
2. Use this software: http://www.techpowerup.com/forums/th...-aware.112556/ It allows your wow.exe to use more Ram

I deleted the WOD models and everything is working fine now, huge difference, thanks.
