I am about to build a system primarily for video encoding. It looks like Intel has a better offering in this category (quad core), and I am a little confused as to which CPU is the best bang for the buck. Any recommendations would be appreciated. I am trying to keep the CPU cost below $300. $200 or less would be even better, but I want a CPU that I can live with for a while. I build and upgrade my own systems, but I rarely just update CPU's in older machines (if that has any impact on the platform that you would recommend).
