I've been using Arch with Nvidia, and it took ~2hrs my first time installing Arch and ~30min my most recent time (different machines), and once it's installed, I only mess with it if I need some software package, and that's usually just pacman -S package. By the time I've installed everything I want, I bet I've spent less time getting Arch set up than the Windows install that comes with my computer (tracking down software on Windows sucks, on Arch pacman gets it done quickly). If you're using Nvidia, most distributions (except Free Software zealots like Debian and Fedora) include their proprietary driver in the repositories, and honestly nouveau is quite good for most things. If you have the choice, go for AMD cards and they'll work much better out of the box.
