I see that in the used market, Core2Duo isn't THAT much more expensive than the CoreDuo. However, is the difference in performance substantial? On Apple's macbook page, it says that the Core2Duo is up to 38% faster in some instances. Truth? I'm looking at 1.83 ghz C2D and CD.

Don't put much weight on Apple's "Up To ##% faster" advertising.

Core2Duo is a bit faster. The main difference is you can use 2 Gb RAM modules, and go to 3.3 Gb RAM (that's what you can use of 4 Gb total installed). The additional RAM makes a big difference when you are multitasking heavily or using Photoshop, digital audio or digital video production programs.

Hmm, I've never used more than 512 mb of ram anyhow. I don't think I'd ever use the maximum of 2gb.

What is the big hoopla about the Core2Duo being 64 bit? Is that relevant?

Core Duo unfortunately is only 32-bit.
Core 2 Duo on the other hand is 64-bit and thus supports all of Leopard's 64-bit enhancements. With 2GB of ram or more you should see a substantial difference which in certain apps could reach as high as 40% or higher. Cinema 4D is a prime example of this.;)

with the introduction of Leopard, everyday 64 bit apps are becoming a reality.

Core Duo does not have 64 bit.

A bit of a tangent; If I were to pull the Core Duo out of my Mini and put in a Core 2 Duo, would it utilize all of Leopard's 64-bit features, or does the chipset of the Mini restrict that? Could it also use 3 gb of RAM?
