So if you are an every day user then the i5 would be fine? Or is it worth spending the extra amount to get the i7?
The i5 should be plenty of power for almost everyone.
I will be using mine purely for writing. Some web research and email, but mostly Word One Note and Scrivener. For my use the i3 would have probably been okay. But I tend to run a lot of apps open at once and would have hit the wall with 4 GB of RAM.
None of these machines are going to be great game systems because for the integrated graphics. They may be decent but that's about the best you can hope for, so you don't need an i7 processor for gaming. If you are doing a lot of serious graphics or video editing, or heavy financial modeling in Excel, you might need the i7. But for normal users that do word processing, email, web browsing, listening to music and watching YouTube videos, the i5 packs plenty of power.
The only other reason to go up to the top model is if you need the 512 GB of storage that will be available.
