It is not necessary to spend a lot of money to edit videos effectively. The computer used in these articles is a Lenovo dual-core with 4 gigabytes of RAM and a 250 GB hard drive. I paid less than USD 100 for the entire computer as I scrounged the monitor and a few other components. 8 GB of RAM would be better, and it would be nice to have more resolution than 1024x768, but I want to emphasize that it is not necessary to have a fancy set-up.
