3 Reasons Not to Upgrade to DDR5 for an RTX 4090 at 1440p

You are CPU-bound, not RAM-bound At 1440p, an RTX 4090 is often waiting on the processor. Upgrading from DDR4-3200 to DDR5-6000 typically yields only 3–5% gains in a few CPU-heavy titles, and often falls within the margin of error.

The cost is not worth the negligible performance A new motherboard and DDR5 RAM costs over $300 for frames you will not notice. That money is better spent on a 4K monitor or a faster CPU later.

This is not where your missing performance is The upgrade does not address the actual bottleneck. You will get more real-world improvement from other upgrades or simply saving your money.
