DVI TiBook 667: 60GB 5400-rpm worth extra $300? Options

[WannaMac]

I will be using a DVI TiBook 667mhz for simple voiceovers and perhaps some singing; probably not going over 4 tracks at most. I read on some discussion board of someone routinely using the stock internal HD (4200-rpm) without a problem for just a few tracks.

So, would the slightly higher RPMs AND extra space be worth another $300 in this case?

I know ideally you shouldn't use the boot/system disk as a scratch disk, and that 7200 rpm is recommended, but I've heard from a few experienced folks that for real-world use, it wouldn't be tragic for my purposes, and this is an immediate purchasing decision.

(Please stick with the 667 model in this instance)

Thanks.

IMO it's no big deal to record from boot disc (for a few tracks of course...)
