Buying a computerโฆ especially for workโฆ well, it's a more philosophical and existential questionโฆ
I have Intel and NVidia, as you can see.
In general, yeah, it's better to do it and see what happens.
Everyone has his own experience. Here's an example. I had a situation similar to that of @kuligs2. I bought and assembled a computer and it wouldn't start. Then I went to the store where I bought the motherboard. I was shown there that it works with other memory. But Asus and GeIL cannot be incompatible! (At that time for sure, but how it is now โ I don't know.) On the way back I went to the store where I took the memory and said that it didn't work. They looked at me with great surprise and without saying a word immediately changed the set. This memory worked for several years until it was replaced with a larger capacity. So, even the most reliable manufacturer can be defective. It's something to keep in mind. So, from a similar situation we found different ways out and made different conclusions.
Right now, you're taking a computer for studying. When you start working, it will most likely be very outdated.
Keep this in mind. I guess even @kuligs2 won't argue with this. The upgrade capabilities are severely limited by the motherboard.
Here is an example of an open 3D world in Godot. Compiled version for Windows.
You can look at this thread Godot 4 Demo Scenes.
But remember that the most tricked out comp will not make the game for you.
How are you with programming and, most importantly, with math?
