Get an i5, trust me, it’s the most bang for the buck. The Celerons are Intel’s low end. The i7s are great, but expensive. the i3’s are barely a notch above the Celerons. The i5 is the sweet spot if your not a gamer.
Nice article breaks down the different intel cpu’s. I have a i5 instead of the i7 due to cost plus the i7 is only a micro second faster and I am not doing lots of video or 3d rendering or gaming. Keep in mind that the a expensive computer today is the less expensive one tomorrow and you will have people say that is not high end anymore when it was high end a few years ago. Kinda like a car with lots of horsepower, you are not going to use it all going to the supermarket so why pay a higher price for the Porsche when a Honda will do?
