Well, I made a very important decision 2 weeks ago. I kicked off Windows and installed Ubuntu on my beautiful and extraordinary Bioproject machine (a poor fuckin AMD Sempron 2600 "+"!)
And it looks good. It feels good. I'm quite happy sometimes, though the games aren't the best part of what makes Ubuntu such a wonderful choice for a desktop user nowadays. Actually it is a lack of support for a guy who don't know weird shit like programming, bash shell commands, and it's certainly sure that Linux is made by & for geeks. I think I may say that I have had problems with my:
1. videocard
2. soundcard
3. webcam
4. AntiVirus
5. guitar tuner
6. 2nd hard-disk (!)
The only things that I regret are: my infrared software for my (very old now) Sony Ericsson k300i and a very cool game - Rise Of Legends. Ubuntu has a lot of applications, BUT many of them are really spartan, not-so-user-friendly (VLC media player is a good example). I have spent many, maaany hours trying to find solutions for the Logitech x-530 (5.1), and for the settings of my videocard.
Overall, I think that Linux is a very good choice for people who are interested to learn every day something new about computers. Really, you have to spend hours to search Google if you want to know the solutions for why you can't do with Ubuntu something you would have made with Windows. I can only say for me: "I'm not commodity!!!" (probably a lie)
