Performance per core is very important if you use programs that do not benefit from multiple cores.

For example, say an 8-core CPU scores 800 on a Benchmark, while a 4-core CPU scores 600. Depending on what you need the machine to do, you may be better off with the 8-core OR the 4-core. Video Encoding with programs that benefit from multiple cores would run faster with the 8-core, while programs that only use one core (commonly Java things) will perform better on the 4-core because each core scores 125 rather the 100 that the 8-core scores per core.

Also keep in mind the Socket Type. The socket type is what determines what you can upgrade to without replacing the Motherboard. If you purchase an 1155 Socket CPU, you are most likely able to upgrade to an Ivy bridge CPU when they're released. The same applies for AM3+ and Bulldozer. If you find a good AM2 CPU, and base your build on that, you'll have to replace a few components if you later decide you want a new CPU.

Overclocking ability. Most AMD processors are unlocked I believe, which make them far better for low-budget builds than their Intel competitors. The i3 2100 could have been a great choice for many people out there, but due to it's locked multiplier and inability to be overclocked, people decided to either up their budget to get a 2500K or buy AMD. If you want the best performance, only purchase Processors that can be Overclocked.
