Why I like AMD
This will be biased, you've been warned.
AMD is known for great processors and major processor innovation. Their Phenom is amazing and ther Athlon is really cool. Semptron and their v-seires I am the AMD kinda guy. I prefer AMD to Intel or any other processor for that matter.
Intel- Creators of the cool i5 i7 and i3, Intel kicked off the x86 architecture. But I've been using AMD for as long as I can remember and will continue to use it for as long as I live. I find running a computer with an Intel processor for me just doesn't click. AMD has the record holder of overclock speed and AMD actually is cooler than Intel (If the thermal paste is applied properly.) Intel is not for me.
