All of these programs require a significant amount of RAM or Random Access Memory. Nowadays, 2-4 Gigs of RAM will suffice. However, there are other factors like video cards, which affect the performance of your computer. It is a good invesment to spend on RAM so that you will not experience slowness while you work or play a really nice game.
