This build should be perfect for gaming at 1440p or 4K even if you have a 4K monitor and optional working and keeping most of what you wanted without splurging on too much. The extra money you save can go towards case fans, accessories like RGB lighting, expansion cards if you need it. Anyways, happy building!
