Brother has a system with i9-9900KF 32GB RAM and the 12GB RTX 3060. He feels it's not up to the 4K gaming he's wanting to get involved in soon, mainly Starfield and the next slew of AAA releases. What in the range would best suit him? Scared of touching the 4090's due to the whole melting scandal. Any solid options under that to do the job and come in at decent cost?
