I the refurb 21.5 3.06GHz Intel Core 2 Duo is now selling for 1099 and a new 21.5 with 3.06GHz Intel Core i3 processor is selling for 1199. Both appear to have the same ATI Radeon HD 4670 card. Which do you think is a better buy? It would be a first iMac. No heavy duty photo editing...basically just a browsing, email, office, etc. Thanks.
