I prefer Intel, but being short on money I built an AMD kit. While shopping around my friend being biased to Intel showed me this unbiased site where they test various CPU's and update their results daily. About 3 inches down and on the right you can select the category of CPU's being compared. Very interesting site and will hopefully put some truth to common speculation.
