well, it depends what you're doing, too. When I'm doing audio/video editing there is a great deal of additional performance from my striped drives. And while the gains for things like loading a game might not be as large, I've certainly noticed them none the less. I find it extremely annoying whenever I have to work on a machine that doesn't have striped drives, the difference is quite noticable, especially after having gotten used to the machine I use most having striped drives. If you only have sporadic experience using a machine with striped drives then the differences might not be too apparent, but once you get used to a machine with striped drives you can easily see the difference when you go to a machine that doesn't have them.
