RAM is one of the most impactful and affordable upgrades you can make to a gaming PC — and one of the most misunderstood. Too little and your PC stutters, struggles, and slows down noticeably. Too much and you’ve spent money on capacity you’ll never use. This guide explains exactly how much RAM you need for gaming in 2026, when upgrading makes sense, and what to buy.
