Install stuffs

yum install chromium virtualbox thunderbird firefox pidgin tightvnc synergy-1.3.1-1 kernel kernel-devel gcc-c++

Now I recommend that you block a few things from updating.

vim /etc/yum.conf
exclude=synergy* kernel* firefox* thunderbird*

video drivers

32bit OS with an 8 series video card (ie 8400gs)

cd /root
wget http://us.download.nvidia.com/XFree86/Linux-x86/290.10/NVIDIA-Linux-x86-290.10.run
chmod +x NVIDIA-Linux-x86-290.10.run

64bit OS with an 8 series video card (ie 8400gs)

cd /root
wget http://us.download.nvidia.com/XFree86/Linux-x86_64/290.10/NVIDIA-Linux-x86_64-290.10.run
chmod +x NVIDIA-Linux-x86_64-290.10.run

Now after these have been obtained su - to root, then run init 3, once you are at runlevel 3 type the following:

/root/NVIDIA-Linux-x86(tab complete it for the arcitecture you downloaded)
confirm through yes on everything.
when back at prompt type reboot.

This should be enought to get you going. will add more soon.
