If you need the best performance possible performance in After Effects, this workstation with an Intel Core i7 9700K or Core i9 9900K is currently the best you can get. There are certainly more expensive CPU options available, but the latest versions of Ae are not able to take advantage of higher CPU core counts which makes the relatively affordable "consumer" Intel CPUs the current king of performance.
This platform supports up to 128GB of RAM, a range of NVIDIA-based video cards, and features dual Thunderbolt 3 ports. 10G networking and a Blackmagic Deckink video monitoring card are also available.
