I'm planning to upgrade my graphics card before used-card prices rise further. I currently have an RX 6700 XT borrowed from my brother and am considering two second-hand options: an RTX 3080 Ti for $380 or an RTX 4070 for $491. My main goal is high-refresh-rate gaming at 1440p, so I'm wondering whether the RTX 4070's newer features and frame generation justify paying $111 more. I'm also open to other GPU suggestions. My system has a Ryzen 5 5600X, 32GB of 3200MHz CL16 memory, a 1TB M.2 SSD, and an 850W 80+ power supply.

At those prices, I’d lean toward the RTX 3080 Ti. It offers considerably more raw performance for the money, and $380 is a strong deal if the card is in good condition. The RTX 4070 is newer, more power-efficient, and supports frame generation, but that may not be worth an extra $111 if you mainly care about standard 1440p performance. Check the 3080 Ti’s temperatures and condition carefully, since older cards may need new thermal paste or other maintenance.
The Ryzen 5 5600X should be usable with a 3080 Ti at 1440p, especially when you’re aiming for higher visual settings, but it can become a limitation in CPU-heavy games or when trying to push extremely high frame rates. If you notice inconsistent frame rates or GPU usage dropping well below 100%, an upgrade to a 5600X3D or 5800X3D could help without replacing the whole platform.

That’s helpful. I’ll keep an eye on CPU usage and frame times rather than assuming the processor will hold the card back in every game.
