I am trying to install Ubuntu 24.04 in my PC, but it seems that it does not work that well with my video card (GeForce GT 620). It only works with the nouveau drivers, which have abysmal performance, especially for youtube. If I try to install the nvidia dirivers with sudo apt install nvidia-driver-460 for example, the system won't boot.
So, is there any way to have good performance for my video card, or should I buy another one?
There is no need for you to buy a newer graphics card. Extended Security Maintenance (ESM) extends Ubuntu's support lifetime from 5 years to 10 years for LTS versions of Ubuntu 14.04 and later. ESM is offered by Ubuntu Pro for free for personal use on up to 5 machines (limitations apply). All you need is an Ubuntu One account.
From the standpoint of extending the usable lifetime of your GeForce GT 620 graphics card you get an extended 5 years of support (until 2032) which at least saves the money it would cost to buy another graphics card which you don't need. My suggestion is to try to install the proprietary Nvidia graphics driver on Ubuntu 22.04. At some point you might consider putting this package on hold to prevent it from being updated. That way a software update won't be able to ruin your current proprietary Nvidia graphics driver installation.
To install the Nvidia proprietary graphics drivers that are compatible with your GeForce GT 620 you might also need to enable the repositories for older releases that are not supported by following the instructions in How to install software or upgrade from an old unsupported release?.
