The presence of two Thunderbolt ports used to connect the iMac 27 "to two external displays. You'll have no problem to connect two Apple Cinema Display 27": Use two mini-Display Port cable (same connector as the Thunderbolt), and any ... work of 81 inches diagonally. If you use a screen of another brand or a former Apple screen, you will need an adapter: your adapter VGA, DVI, HDMI to Mini Display Port working perfectly. The only problem will come from screens 30 "you should use a dual-link adapter, an active housing costing hundreds of Euros.
Otherwise, the ports are used to little Thunderbolt: devices using this new standard, although promising, will not arrive until mid-summer. Intended primarily for professionals, promises to be cost prohibitive and limited uses for the moment, the interest of this new connector is limited to the general public.
This is not the case for other race horses of the new iMac. The processor is an Intel Core i7-2600, the fastest second-generation Core i7. It has four physical cores, identified as eight logical cores (hyperthreading) clocked at 3.4 GHz. When an application does not use all cores but needs power, the processor can disable cores dynamically to increase the frequency of the remaining cores: it can go up to 3.8 GHz on a heart (Turbo Boost). With all reasonable thermal envelopes in this range, 95 W is worth mention (32 nm etching).
