If you’re debating between getting the new MBP (i.e., the ones with multitouch and Penryn processor) or the old MBP, you’ll find AnandTech’s benchmark tests very informative.

The net: Penryn’s biggest advantage is in battery life. Performance is a tad better (depending on the test) but not a lot. So, for some of you, the reduced prices of the old MBP may be the right option for you.
