When Apple released new iMacs in early May, the company also made available new build-to-order (BTO) options in addition to the standard-configuration models. Macworld Lab tested two iMacs with BTO processor upgrades that offer faster speeds and more processing power, and the results show that the additional cost for the upgrades are worth it--if you run software that takes advantage of the technology.
