I promised you that I will let you know my experience when I install a separate graphic card.
I plugged in a ATI HD5770 PCIe card into my machine and after struggling with the installation of the AMD drivers, I finally succeeded to install the drivers on ubuntu 12.04 64bit kernel 3.2 as show in the following uname output: Linux Asus 3.2.0-24-generic #39-Ubuntu SMP Mon May 21 16:52:17 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux My setup now is Asus P8Z77-V LX motherboard with I7 3770K + 16GB Ram + ATI HD5770 GPU on Ubuntu 64 For two days now, I did not experience any system freeze ; Neither Xorg nor complete kernel freeze. I even enabled multi-threading in FlightGear which used to freeze the system very quickly when HD4000 was used, but now it works fine. I hope this comment will help those who are working on this problem.
