Only my 2 Cents but if you are going to work on AI or machine learning, maybe try to get a GPU with 24GB of VRAM like a RTX 3090, even used. You can maybe have a read at the following thread I link where we basically let large models like Deepseek run on modest hardware completely locally. But a GPU with 16GB VRAM is very limiting, 24GB is better.
Here is the thread, might be interesting to you.
