I'm looking to upgrade my current Sapphire Nitro+ RX580 for a productivity-focused build. My main requirement is to run three 4K monitors, each at 120Hz. I'm not into gaming or video editing, so I'm focusing strictly on productivity tasks like Excel, Power BI, Databricks, and streaming video. I'm currently eyeing a used Gigabyte NVIDIA GeForce RTX 3070 Eagle OC 8GB on eBay for about £250. Is this a solid option, or should I consider something else?

With three 4K monitors, any standard GPU should handle your setup fine, but you might want to verify the outputs on the GPU to ensure it can support that configuration. I run a 4K160 and a 4K120 without issues on my RX6900XT, but notice the wattage can go pretty high when both are active.
Honestly, you might be overestimating the demands. For basic productivity without any 3D rendering, most GPUs can cope with three monitors at 120Hz. You might be aiming too high with your expectations. Even lower-tier GPUs can manage this if you're sticking to 2D apps.
You may not need a high-end GPU for just Excel and similar apps. Integrated graphics can handle 4K at 120Hz for basic tasks. What are you actually using it for? If it’s just simple productivity, you might not need an expensive card at all!
Good point! I have Databricks, Palantir, and multiple 4K YouTube streams running. I noticed how much smoother 120Hz feels versus 60Hz at work, and I want that experience at home.

Exactly! 2D applications don't require as much from your GPU as you might think.
