We used to tewll our customers to stick with Intel. Witht he latest round of dual-core processors this is no longer the case.
Back in the end of 2005 we realized that our first two DIY projects had gotten pretty long in the tooth. While they were pretty cutting edge at the time, we were seeing some very new and exciting technologies breaking out. The most exciting was dual core processors.
The advantages of Dual Core processors for video editing are significant. The biggest is price / performance. Most video editing applications are written to take advantage of dual processors and hyperthreading, now with a single affordable chip, you can maximize this capability.
With a Dual-Core processor the installation and set up of our DIY4 machines was very easy. As you will see from this article, you can build a killer dual core workstation for under $2,000 that will give you outstanding performance for all your editing and encoding needs.
