I got my first Mac (15" MacBook Pro) in late June, so I will be receiving my Snow Leopard disc within the next week or so. This will be my first reinstallation of OSX. I will not do an upgrade however - I'm still going to do a clean reformat/reinstall. So, is it necessary to do additional driver installations once you have finished installing OSX? I know on a Windows machine, after you install the OS, you really need to go through and install drivers for most of your hardware. I'm wondering how this works with OSX.
