I'm a 3D artist who mainly uses Blender and Cycles, with the GPU used mostly for rendering. My scenes usually don't contain extremely high-resolution textures. A client and friend suggested buying the 16GB version of the graphics card for future-proofing, but it costs nearly twice as much as 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'd get more benefit by upgrading other parts of my system. My current PC has 16GB of system RAM, a Ryzen 5 5600X, and a 700W power supply. I'm considering an RTX 5060 Ti, either the 8GB or 16GB model.

VRAM matters when the entire scene, including geometry, textures, render buffers, and acceleration data, needs to fit on the GPU. If an 8GB card runs out, Blender may fail to render on the GPU or fall back to system memory, which can be dramatically slower. If your current scenes comfortably fit in 8GB, the 16GB model won’t automatically make them render twice as fast, but it gives you much more room for larger projects later.
For Cycles, prioritize a capable NVIDIA GPU with good OptiX performance, then decide based on the size of your actual scenes. If the 16GB card would put you under serious financial pressure, don’t buy it solely because it might be useful someday. Check your current VRAM usage and benchmark the exact cards you’re considering. A used or open-box higher-tier card could also offer better rendering performance, while upgrading to 32GB of RAM later would be sensible.
I’d consider upgrading to 32GB of system RAM as well. Sixteen gigabytes is workable, but Blender projects, background applications, simulation caches, and compositing can use it up quickly. A balanced setup with 32GB of RAM and 8GB of VRAM may be better than spending everything on VRAM, unless your Cycles scenes are already exceeding 8GB.
Since your textures aren’t very large, 8GB may be enough for now. The important thing is whether your scenes are already close to that limit, not just how much VRAM sounds better on paper.
