What GPU would be a worthwhile upgrade for my Ryzen 5 5600 build?

The RX 9070, RX 9070 XT, RX 9070 GRE, and RX 9060 XT 16GB are worth checking if current prices in your area are reasonable. I’d prioritize at least 12GB of VRAM. Nvidia cards tend to be harder to justify on price unless you find a particularly good deal.

For 1440p, an RX 7700 XT is a strong match for this system, especially around $350. It has 12GB of VRAM and should handle high settings well. An RX 6700 XT is also a good used option for 1080p ultra gaming, while an RX 7800 XT would work but may run into some CPU limitation.

The Ryzen 5 5600 can support a fairly substantial upgrade, but I probably wouldn’t go much beyond an RX 7700 XT or similar unless you plan to replace the CPU later. A faster card like the RX 9070 XT will still work, though its performance may be limited in CPU-heavy games until you move to a newer processor.

The final recommendation depends heavily on your budget, monitor resolution, power supply, and local pricing. If you’re buying new, compare the RX 9060 XT 16GB and RX 7700 XT first. If shopping used, a 3060 Ti around $200 or an RX 6700 XT can be excellent value.

The RTX 4070 Super and RX 7900 GRE are previous-generation cards, so I’d only choose one if it’s clearly discounted. Used options such as the RTX 3060 Ti, RTX 3070, RTX 3080, RX 6800, or RX 7800 XT can offer good value, but check their condition and power requirements carefully.
