Is a Casio fx-9750G good for A-level further maths?

I currently have a Casio fx-9750G graphical calculator I got a long time ago, but haven't used it until starting a-level further maths. I haven't had to use it much, and got quite used to it. However, this calculator is extremely old and displays some data in a very strange way, meaning I sometimes have to do extra work to get the answer I need.

My question is, would it be worth it getting a newer one? I'm asking as eBay are doing a 20% off everything until 10PM today (saving myself a fair bit of money, as graphical calculators tend to be expensive), so I thought that I might as well get myself a newer one if it's going to be an improvement. Also, are there any you would recommend if so? Thanks in advance.
