I recently have gotten into video, such as downloading .mkv files from Vuze, and .mov and .avi files from various other places. Now that I will be purchasing a Mac mini I hope to watch movies from the iTunes Store. One of the things I hated about my Power Mac G4 500 is that it's slow processor could only play about 45 percent of the videos I had. The rest of the videos I tried either the audio and video would either out of sync, just sputter along, or refuse to play at all. Will the 2.0Ghz processor of the new Mac minis be sufficient for video, or do I need to go with the 2.26 Ghz processor offered in the "build-to-order" option?
