I am in the process of acquiring a new notebook with the primary 
function being to run darktable. Are there specific areas of primary and 
graphics processor that I need to be aware of in order to use dt's full 
functionality?

I am currently consideringpurchasing a Lenovo W520 .... does anybody 
have experience of this machine, with dt,  running under Ubuntu?
