Classic Athlon
Celeron is intels low-cost processor. It is meant for people who do not require a powerhouse CPU, and thus has a bit less processing power than its non-celeron equivalent. AMD's low-cost alternative to the athlon is the duron. So you have a choice between a low-cost intel, and a high-dollar AMD, which is pretty much a draw. When you add the 2gb or RAM, it becomes obvious that the AMD is going to be the better performer.
