Let's not forget the audio interface, its interface technology and its
drivers here. The combination can make all the difference here, and it's
also something you can choose rather freely (other than, say, the firewire
chipset of a laptop).

The tuning is in fact an important factor here. There's lots of websites
which describe how to tune your OS so it runs best for audio applications.
For my main machine, I actually use two independent OS installations, one
for music and one for all the other stuff.
Another item worth mentioning that hasn't come up is the so-called DPC
latency. This is a property of the computer hardware and lowlevel software
(read: BIOS). Especially for laptops, this value is sometimes over the
but can be possibly brought down e.g. by disabling wireless network
Here's a tool to check this: http://www.thesycon.de/deu/latency_check.shtml
