If you are going to be doing heavy video editing/rendering AMD will suit you much better and will be cheaper. AMD has always been good at pure clock speed and power. In most applications it cant be used effectively due to software limitations (only using 1 core). Thats where intel beats it with architecture. But for programs that use all cores (most video editing software) and some games like battlefield 3 that use all cores, AMD will beat an intel any day.
