Currently have the C2D 2.93 and have had it quite a while and am just wondering how much better the i7 will be over the 2.93.
Tempted, but if its just marginal improvements I may skip it.

Thanks, interesting that you cant get the 2.93 i7 now, the 2.66 is the only one listed on the site.

The 2.66GHz i7 is about 40% faster than the 3.06GHz C2D according to my own tests for multithreaded applications. It's 60% faster for single-threaded applications.

2.93 Core 2 Duo MacBook Pro:

2.93 Core i7 iMac

Roughly 2.2x faster in multi-threaded apps.
The i7 in the iMac is not only clocked higher than the i7 MacBook Pro, it is also a quad-core part.

Not a good comparison.

Don't the two use pretty much the same components though?
Graphics wise they both use mobile versions of the cards, but the newer iMacs use desktop processors which put out more heat and can therefore run more cores and faster clock speeds.
