[QUOTE="nko, post: 8739"] DirectX is a Microsoft / Windows only thing, but many games can also be played, even in Windows, using OpenGL. The difference is in which graphics system the game uses to render scenes (and I think sounds, too). DirectX is much better for gaming, but OpenGL isn't bad at all. Just a little mention, on my Pentium 4 with 384 MB / RAM, UT 2003 ran at only 4 fps less in Linux than in Windows. Linux was using OpenGL, Windows had DirectX. Windows of course had the whole OS loaded at the time, while Linux had the kernel, drivers, X windows system, and a very small Window Manager (basically meaning I wasn't running anything that would block performance, which is flexibility that adds performance). Also, I may be wrong, but the game was designed originally with Windows in mind. Besides all this, OpenGL on a dual G5 will probably kick the pants off any Pentium system, and do similar work against an AMD. Something you might wanna look at, if you wanna get really excited about multimedia content creation on the G5 you're thinking about, is a video of Steve Jobs' keynote speech at the World Wide Developers' Convention 2003.
