so i switched myself and my parents to arch linux over the past 3-4 months and I can say definitively that those specs are fine for CachyOS (an Arch Linux distro). My mom is using my hand-me-down 970 with its lovely “we charged you for 4gb of vram but actually only 3.5 of it is fast haha sucker” and it runs great paired to an old i7 6700k
