Sorry to be another person of "hey should I buy a new computer?", however I don't have much idea about laptops as my current Macbook Pro I got was back in early 2014 and has been my only proper personal laptop that I've had.
My parents have offered to buy me a new Macbook Pro before the start of Uni (possibly buying the 2018 update as I've heard the 2017 model has had problems), but I have suggested maybe updating the hardware in it so that it will hold out til the end of my undergrad degree.
The current specs of the laptop:
MacBook Pro (Retina, 13-inch, Early 2014)
2.6 GHz Intel Core i5
8 GB 1600 MHz DDR3
In terms of what I have on the laptop / use it for, I don't really play games or have anything like that on it, but I do use Photoshop and Logic Pro X to make music and whatnot, and at times it sounds like my computer is about to brick itself processing things, but hasn't yet and has been quite reliable so far.
So is it worth spending £1500 for a new Macbook Pro for the start of uni, or will my current laptop be fine for the next 4 years (I say this as I would rather keep the same laptop over the length of the course so I can collate and keep notes and not have to worry about transferring files).
Thanks for the help, as genuinely unsure!
