I just got this info from everymac.com The iMac "Core i7" 2.93 27-Inch (Mid-2010) technically is a "configure-to-order" configuration of the iMac "Core i5" 2.8 27-Inch (Mid-2010), but also is documented as a separate model for reader convenience. Other than processor, these two models are identical. The iMac "Core i7" 2.93 27-Inch Aluminum (Mid-2010) is powered by a Quad Core 2.8 GHz Intel "Core i5" I7-870 (Lynnfield) processor with a dedicated 256k level 2 cache for each core and an 8 MB shared level 3 cache. In lieu of a system bus, it has a "Direct Media Interface" (DMI) that "connects between the processor and chipset" at 2.5 GT/s. WTH, is it i7 or i5? Can somebody here explain this? I just bought this system, and want to make sure it is an i7.
