What? None of these worthwhile?
There are entire websites devoted to linux gaming and lists of modern games that do work and at what level and they ain't exactly playing Pong. Beyond that and considering the mess of DRM and Malware, why not either buy a game console or use windows for games that won't run satisfactorily in Linux (w/ networking disabled to avoid all those ridiculous infections of course), and Linux for all the heavy lifting?
You might say such-and-such a set of programs keeps my Windows running fast and smooth, but doesn't that imply it is broken by default if you REQUIRE fixit programs (or annual reinstalls) to keep it running in a reasonable fashion, programs that cost you $$$$ too. As for security, there is basically none in windows since it asks you to shoulder the blame by "Cancel" or "Allow". That's not security. That's dodgeball.
Just how far are you willing to go? How much will you keep on paying to have a viable system? You are Ballmer and the Boys' personal cash cow if you keep coming to the trough.
At the very least it is worth a little time to learn Linux so you know you can break the habit once you get sick and tired one time too many.
