Please recommend a desktop PC system that works well with the Adobe Premiere Pro, Encore, and Photoshop. I currently use a Dell Precision 650 workstation, but it is about 4 years old and I have had to have it repaired too often. I need to upgrade to a new computer and my boss said to find something really good with lots of storage and speed. I would also like a computer from a very reliable company that has excellent telephone tech support packages. I use the computer to edit and build training DVDs that are usually around 300 Gigabytes. I store my finished projects on Maxtor External Hard drives.
