Is a 5070 12GB GPU Too Much for My Build?

Honestly, if it were me, I'd steer clear of the 5800X3D for a new build. AM5 is around the same price and would give you better performance long-term. But since you're committed to the AM4 motherboard, the 5070 will work just fine. Just be mindful of what games you're playing and the settings you're using.

You’ve got 240Hz lined up for your monitor, which is great for fast-paced games like Overwatch. The 5070 should manage that with high settings. If you're also into rendering 4K videos, that’s where the extra VRAM could be beneficial. Honestly, if you’re feeling stuck with the current setup, maybe consider a future upgrade to AM5 when the budget allows, but for now, the 5070 is a good match.

If you plan to run demanding games at higher settings or 1440p, consider aiming for a GPU with 16GB of VRAM. The 5070 is good for 1080p, but for more demanding settings, a 9070 or 9070XT could be a better fit down the line. It's all about your gaming habits!

Considering that you're already on an AM4 platform with the 5800X3D and 64GB of RAM, the 5070 is a solid choice. If it fits within your budget, it's not overkill—it should handle your gaming and rendering tasks quite well. If you're looking to future-proof even more, maybe consider the 16GB version or a 5070 Ti if you're okay spending a bit more. Plenty of traditional cards like the 3070 are also still good options, but the 5070 is really a great pick right now.

Lastly, just to clarify, the 5800X3D isn’t a bad choice for what you have planned. It can handle the load effectively. Just make sure you factor in your use case (like those 4K renders)—that might shift your GPU preferences.
