I have recently built an Intel c2d e6300 with both cores at 1.8GHz I used to have an AMD 4200. When running a single process it is like having a pc from 2 or 3 years ago, a bit slow. When software is available that takes advantage of dual cores it will be much quicker. Where the present setup scores is when I have 2 things running at the same time. Instead of the cpu giving a bit of op time to each process in turn, most noticable by jerkiness of pictures etc., now both processes keep running without interuption one on each core. Hope this helps.
