Nice payouts! I just got my first payout last month, I do not share as much room as you, but still I never notice it running, its very good resource wise. I know my cpu's hardly ever see more than a 30% load on average %14 or so..And I think about a gig of ram and one cpu per share is good. So on a cheap quad core with 4gb ram its easy to run 3 or 4 shares!
