Which graphic drivers should I Install and how?

view story

http://serverfault.com – I have a system on which RHEL6 is installed. I need to install proper graphic drivers. I checked my graphic card simply by this command #lspci -v | grep VGA 00:02.0 VGA compatible controller: Intel Corporation Device 0162 (rev 09) (prog-if 00 [VGA controller]) When I searched its drivers I found this (01.org/linuxgraphics/)link. But I don't know which drivers to choose and how to install them. (HowTos)
