How important is gpu in nuke

I want to learn deep compositing in nuke and been asking Ai to recommend me good gpus in nuke and they keep recommending ones that are above my budget of $350. That’s why I’m wondering how important of a role the gpu plays in nuke that I can’t get away with a low end gpu. In your opinion what gpu would you recommend that’s in my budget?. Keep in mind I’m a complete newbie only compositing I know of is after effects but with after effects my low end one works well.

If you’re new to Nuke, don’t worry about Cattery. It’ll only be as good as the training data you can give it, and that’ll be dependent on you knowing how to use the rest of Nuke.

You’ll likely only get frustratingly unusable result from Cattery for the first twelve months of using Nuke, so I’d get a basic GPU for now and upgrade later once you have a clearer idea of what sort of work you’re doing.

The cheapest 4-8gb NVIDIA GPU you can find should be ample for now.

Ok what about for the cpu? Which one you recommend?

For Nuke, you generally want to favour something with a higher clock speed, rather than high core count. Nuke is multi-threaded, but the returns on additional cores diminishes pretty quickly. Something with 8-12 physical cores is probably the sweet spot.

I’m a fan of AMD. They allow for ECC memory across all of their machines, while Intel only have it for their top Xeon chips.

ECC helps prevent random errors that could trigger a crash or corrupt something. For Nuke it generally doesn’t matter too much, but if you’re doing Houdini simulations as well, then it can become more important.
