If you are looking for the performance for a budget then take a look at AMD's APU's. They are processors with low-end graphics built in to them. They are really cheap and provide good performance for the money. Usually they are socket AM3 and AM3+, the models are AMD A6, AMD A8, and AMD A10. The performance increases with the number as you can imagine.
Hope this helps. Cheers.
