Linux is great if you want full customization/know how to go in and change things. The down side is nothing really supports linux, im not sure if the truck packs work with linux. There is also the steam OS which uses a version of linux. More and more steam games are supporting linux so that might be an option. My opinion is just use windows 7, or use linux for a few months and get windows 10, I think its set to launch later this year.
