A gaming rig has different needs to perform well. Although a good gaming rig can also perform well as workstation, i would not advise to do so.
However, I decided to go with an AMD Threadripper 3960x
instead. I made this choice deliberatly, mainly because I like to work with DAZ3D and other 3D modelling kinds of software. The threadripper rins on a ASUS ROG Zenith II Extrme Alpha
My current gaming rig is based on AMD. I did consider using intel (Intel Core i7 10700K or Intel Core i9 10900K) as a platform. Both processors are (now) affordable. Alternative could have been waiting until november 2020 and AMD's new lineup or use the AMD Ryzen 9 3900X.
