It looks like you're planning on using windows, in which case I would strongly caution against only 8 GB ram. I have a 4 year old windows laptop with 8 GB RAM, and unless you do a lot to optimize things/kill processes it quickly becomes slow to a very frustrating point. The last thing you want is to open a new tab to look up something the professor said while running a note taking app and have the whole thing freeze for a few minutes and not be able to take notes. RAM is relatively cheap, so I would bit the bullet and either get 16 GB or run Linux.
