refurbished macbook - what specs to watch out for

[bob2131]

hi, im looking at macbooks, refurbsished. and im noticing often, lesser figures, and even sometimes higher figures.

- L2 cache
- system bus

im gonna be buying a macbook for music production. are the above things important? like the cache fig is 2, 3, or 4mb, and the system bus is like either 800mhz or 667mhz.

is there any figures that i shoould not settle for??

i mean i know about the obvious ram and processor etc.

just wanna ask, about the not so obvious specs that you need to look out for.

thanks
