I just bought a new mid-2010 updated iMac with 2.8GHz Core i5. However, when I looked at the system profiler, it reports CPU speed at 2.66GHz. At first, I thought I accidentally got the late-2009 version, but other aspects of the system seem to indicate that this is correct Mac. The box has updated part number, but does list the CPU as 2.66GHz. It has the newer HD 5750 w/1GB RAM, it uses 1333GHz DDR3 memory. So everything seems to point that it's a new iMac, but the CPU is of the wrong version. Has anyone heard about this? Anyone know what's going on? Help appreciated.
