You might not notice any difference in the games you play, Mr. Zealot, but benchmarks show that those playing games which demand the best hardware, would be a lot better using an AMD CPU. The very high-end (and over-priced) Intel chips beat the lower Athlon 64's and Semprons (much cheaper), but not by much, and the price difference just doesn't really justify paying a lot more for a CPU sucking your PSU dry and putting up energy bills and waste.
