The advantage of dual processors is that you can use the
machine for several things at once, including multiple R

Dear R Users,
I hope that there is someone who has an experience with a problem that I
describe below and will help me.
I must buy new desktop computer and I'm wondering which processor to choose
if my only aim is to speed up R. I would like to reduce a simulation time -
sometimes it takes days.
