Trainz and about 15 other sims/games.
When you have real experience (not speculation) with hardware then maybe you can consider yourself a good source, lol.

If you knew what you were doing aside from buying the most expensive machine available and parroting other people's statements, you'd realize that other people have different needs and adjust your advice accordingly.
