Yep.
I upgraded my E3300 to a Pentium Dual Core E6500 and an increase of about 1300 ppd. Also, Newegg had a deal a couple weeks ago on GT-240 card. Net $39 after rebate. I was unable to get the previous card to fold (HD5450) in that box so I said what the hey. The 240 gets about 4000 ppd. So about 7k ppd total because the Celeron was getting about 1700. That and the box in my computer specs is my little folding farm.
