To put it simply: Intel is in generally more expensive, but AMD is generally behind Intel in performance when it comes to each of the company's high-end chips. Intel's new 2nd gen Sandy Bridge architecture Core i3/5/7 chips are some of the best deals nowadays. They just came out a few days ago, and if you need a chip around $225, then definitely check out the Core i5 2500k. It's got an unlocked multiplier, which is necessary for overclocking the Sandy Bridge platform. The FSBs on these new CPUs are virtually un-overclockable for more than 5mhz. If you need a chip for around $320, then get the Core i7 2600k. It's 100mhz faster than the 2500k, and has hyperthreading, which will make it far more future-proof.
