Re: @Ghost, which distro?
Usually the advice for "what Linux system" is "Mint".
Given your interests, though, you might try KXStudio or AV Linux. The main advantage is optimisation for low latency, and preloaded audio / visual software, codecs, and plugins.
You've got all that stuff in spades on Windows, but if you're moving to Linux for connected systems it may interest you to develop some capabilities on those machines too?
