Help between recommendations from CGDirector

Hello! So, I'm a COMPLETE NOOB when it comes to building a computer and just overall hardware in general, but I'm taking the plunge and deciding to build my own PC!

I'm a recent graduate breaking into the animation industry, and my focus is on 2D animation (ToonBoom Harmony, TV paint), but I also like to model and do occasional 3D animation (Zbrush, Blender, Maya)
(I also used after effects for compositing)

My budget is $1500, but of course, if I can get away with spending less without compromising too much quality, I would love any help is finding out where I could save a penny or two! While doing research on here, I used both the custom PC builder, but also looked through the "Best PC for 3D/2D animation at ~$1500" article, and now I can't decide between the two. The two biggest differences I noticed are the CPU and the graphics card - one has a more expensive CPU with a cheaper Graphics Card and vice-versa. When it comes to animation, which would be a better area to focus on: CPU or Graphics Card? Or does it not matter? And are there any other thoughts between the two builds that I should know about!

Thank you so much for listening to my beginner ramblings!

That Build #2 will certainly be the faster of the two for the kinds of workloads you listed. The first build is a bit outdated (will have to update the article you got it from) especially because the Case is horrendously expensive and hard to get which skews the overall budget distribution in that build.

Build #2, though is the one you want right now, it'll give you great single core / active work performance and decent GPU Rendering performance if you're using any gpu render engines.
