intel vs amd

AMD = Smaller Company (use to specialize in cheaper CPUs - although these days they are more expensive than Intel!) = larger processor chip, usually less stable, higher temperatures, slower (and they've also got that model number for speed scam going on). However AMD CPU's are great for overclocking (their FX series allow overclocking).
INTEL = larger company, smaller CPU chip, some processors have lower temperatures and some of them actual go over 100 degrees Celcius (no joke), usually better bang for your buck and has more features. However they are horrible for overclocking (usually you cant at all). But remember that Intel now has dual core processors, etc - so they are faster and better value.

AMD is usually placed with ATI (like AMD they use to specialize in cheap graphics cards, but now are very expensive), and Intel is usually placed with Nvidia. I personally think that Intel and Nvidia are the best, and AMD & Ati are just jokes that went 

this garph shows intel is better than amd
