I'm a 3D artist who mainly works in Blender with Cycles, and I'm choosing a graphics card primarily for rendering. My scenes usually don't use extremely high-resolution textures. A client and friend suggested buying the 16GB version of the card because it may be more useful in the future, but the price is nearly twice that of the 8GB model. I'd have to work significantly longer to afford it, so I'm wondering whether the extra VRAM is really worth it or whether I should spend the money on other upgrades instead. My current system has 16GB of system RAM, a Ryzen 5 5600X, and a 700W power supply. I'm considering an RTX 5060 or possibly an RTX 5060 Ti.

Don’t ignore system RAM either. With only 16GB, Blender can run into limits during modeling, simulation, compositing, or when several applications are open. Upgrading to 32GB is usually a sensible improvement, especially if the 16GB graphics card would force you to make major financial sacrifices. You can optimize textures and scene assets to stay within 8GB, while a system-memory upgrade helps across more parts of the workflow.
VRAM matters when the entire scene needs to fit on the graphics card. If a Cycles scene exceeds the available VRAM, rendering may fail or fall back to system memory and become dramatically slower. So 16GB gives you more room for larger scenes and future projects, but it won’t automatically make an otherwise small scene render faster than an 8GB card. If your work comfortably fits within 8GB, the cheaper card can be perfectly usable.
Choose based on the GPU’s actual rendering performance, not VRAM alone. Nvidia cards are generally a strong choice for Cycles because of their OptiX support, and it may be worth comparing benchmarks for the exact models you can afford. A used or refurbished higher-performance card with 12–16GB could be better value than buying a slower new card just for its memory capacity. If the work earns money, 16GB is a useful investment, but the client should not be deciding how you spend your own budget; if they require that capacity for a project, they should help cover the added cost.
They’re a friend as well as a client, so they were making a suggestion rather than setting a requirement. I’m also considering doubling my system RAM, depending on which GPU gives me the best overall value.
That makes sense. My current projects aren’t especially texture-heavy, so I’m trying to figure out whether the extra capacity is worth paying for before I actually need it.
