Can you record hd with a gtx 660 (with obs)?

I have a question,

I would like to record Minecraft, for example, but I don't know whether my graphics card can record well for Hd. If so, which settings do I have to make in obs. I have i5 1050, can I record with higher quality?

Do you have 1 or 2 monitors?

You mean you definitely have an i5-10500?

Yes I mean that but you can upload Minecraft and Fortnite in one video. I don't mean that I want to make a split screen out of it

Did I understand correctly that you have 2 monitors?
