I want to know if this is a good deal. I've never built my own pc so I was just wondering. i already have everything else but i don't know if i should buy thermal paste or does it come with it? i also only plan on playing games like apex legends, the finals, and resident evil series games.

I recently bought a pc from a friend. I bought it for $80 dollars. it came with a (asus b360 motherboard) and a (i5-9600f). I also bought a rtx 2060 for $70 dollars from him. I was wondering if I should continue with what I have or upgrade something? I had to buy the ram and ssd apart. I got 16gb of ddr4 and a Samsung - 990 eco plus ssd 1tb.
