I have both a PowerPc version and a Intel dual core. Both are fine for playback, the real issue comes down to ripping and multitasking. The Power PC version is slower to rip, and makes more fan noise than the power pc version. Plus, the Intel version lets you run Windows if you want, which opens up more playback options if you prefer a windows player.
I have 512 mb on the Power Pc, and 1 gb on the Intel.
