Ways to Reduce Your Impact
Upgrade your computer
Upgrade your current computer, instead of going all out and purchasing a completely new one. Load it with new software and anti virus, graphic cards, and sound cards, and you are on your way.
However, this should be used for the computer savvy people. Unless you want to take your computer to a shop and have them upgrade it for you. It will be less expensive than having to purchase a whole new system. Including a monitor and mouse and keyboard.
