For the regular tasks like web, text processing, spreadsheets etc, the X Plus is more than enough. You certainly won't be able to tell the difference. If you don't need the top performance, the Plus version is actually better due to its lower power consumption in comparison to the Elite.

Basically the same for web and office, The Elite has 12 cores versus 10, so it's slightly better at multitasking. If you ever notice the difference. The Elite has better GPU, but that's not important for your workflow. On the other hand, you can expect slightly better battery life on the Plus.
