Intel Processor i7 vs i5 vs i3 and Atom Comparison

If money is not an issue, my advice is to always go for the best. Scaling down the processing speed is not an issue; however, boosting up the speed will be an uphill task.

Furthermore, based on my own personal experience, a good processor will power all of your future software while an average processor bought today will not be able to run future software. Making sure your processor has all the processing speed required in the future will save you even more money on the long run.
