"Awesome machine"5.0 starson by shady28
Pros: New Sandy Bridge Architecture; New GPUs are able to keep up with all the current games; 2 Thunderbolt ports make it possible to drive 2 additional monitors, plus 10Gbit/s for external storage and other devices; You can run windows or OS X on it
Cons: Pricey, but still a better deal than comparable Windows based all in ones.
Summary: Simply an incredible machine. I picked mine up this afternoon - way faster than the previous generation.
The chart in the article is incorrect though, the i5-760 is not what is in the new iMac 27 (and is not Sandy Bridge). The 760 was used in the previous generation top line iMac 27" and is the older core i5 architecture.
The new top line iMac 27" uses the i5 2400, while the other models use the 2400s and 2500s. These are the Sandy Bridge CPUs. The 's' versions are lower power processors, with a heat design of 35 Watts vs 65 or 95 watts for normal variants. This means the new iMacs will run cooler than the last generation iMacs.
