If you had to choose between a 2.2 hz quad-core or a 2.5ghz dual-core one, how do you know which is right? In my mind, you’re better off with as many cores as you can possibly get. Even if software is not optimized for maximum cores at this point, it certainly will be in the future.
If an app is designed with multiple cores in mind, you’ll be happier having more cores no matter what the processor speed is. It depends on opimizational code, honestly. Check your benchmarks, and see how the two processors compare.
Dollar for dollar, though, I’d go for more cores rather than the raw speed of the processors.
