I just found the new (I think) i3-3250 over on Newegg and it has a 3.5 GHz base clock as opposed to the 3240's 3.4 and 3.3 on the 3220. The only other difference is that it costs $10 more. Would it be worth the extra $10 for a 100MHz clock boost? Or should I even bother with it and just go for the 3240? Sorry, I'm cheap!
In full honesty Stick with the 3240 because if you would want to upgrade in the future you would not go with the 3250 you would go with an i5! So for now go with the 3240 and then in the future upgrade to an i5.
