I would perhaps buy a Dell computer with video card type "NVIDIA GeForce GTX 750Ti 2GB DDR5", but I don't find this in the list of supported GPUs for Ae. Is it supported or not?
The thing is, on the Dell website other computers are available that are specifically adapted for Ae use. One of these computers has a video card type "2 GB AMD FirePro™ W5000", which is also not in the list of your supported GPUs. So I'm wondering whether the supported GPU-list is complete.
Do not make buying decisions based on the ray-traced 3D renderer. It is an obsolete feature that is being phased out and replaced.
Yes, the system requirements page has an up-to-date list of GPUs supported for this feature.
No AMD card can possibly be on this list, since the feature requires CUDA, which is only on Nvidia cards. That's one of the big reasons that the feature is being phased out.
Whatever modern card you get will be fine for After Effects, since After Effects uses the GPU for almost nothing, and the requirements for the OpenGL features are somewhat low.
Alright, thanks for the info!
