Hi guys well i just want to know whats the best way to do it cause i use a method which i dont know if is ok (by the way it works) but im not sure if my card is giving 100% (Geforce 8600gt), right now im using mys system isSqueeze with the non-free repos, what i usually do to get Nvidia work is this
first i download latest driver from Nvidia then

    apt-get install gcc-4.3 module-assistant
    /etc/init.d/gdm stop
    m-a prepare
    m-a a-i nvidia
    chmod +x NVIDIA-Linux-x86_64-xxx.xx.xx-pkg2.run
    export CC=gcc-4.3
    ./NVIDIA-Linux-x86_64-xxx.xx.xx-pkg2.run
    /etc/init.d/gdm start

and everything seems to work fine, but i wanna know if this method is the "right" method thanx

That's fine, you can rerun it anytime you choose or need to.
I normally do "./NVIDIA-Linux-x86_64-xxx.xx.xx-pkg2.run
--keep" which keeps the directory around, so if you have a new kernel or an update that overwrites the NVidia driver, I cd into the directory and "./nvinstaller" or if it's all there and I just need a new kernel module, I cd down to the ./NVIDIA-Linux-x86_64-xxx.xx.xx-pkg2/usr/src/nv directory and do a "make install".
