My mom is looking for a new computer, she has a small budget and has found a couple that interest her. Each of them has either the i3 2120 or the AMD Athlon II x2 240e. The main programs she uses are Microsoft office and Photoshop, as well as your basic video watching and such. Can anyone tell me which would offer better performance? She is hoping which ever she chooses to last her quite a while. Thanks.
