Can be found for cheap on Aliexpress. Motherboards still competitively priced compared to TRX4 which makes this a fantastic budget workstation choice in 2021 for those who need more than 10-12 cores and don't have money to get a Threadripper.

I will building a new workstation and I forget how many post that I have ever read about it watched bunch of videos and finally I am so confused. I was thinking to buy i9 7940x but that CPU is really bad for after effects? If it is.. only getting render? I do not have any time issue for rendering. I just want to work on huge project like 4K-6K footage and cinemaDNG codec as a live preview. i9 7940x is really bad choose for After Effects? Or the almost the same performance with i7 8700K? everybody is choosing i7 8700K because of price/performance? I have been thinking to fix multi-core issue with rendergarden, if it bothers me So could you help me out please? I am really so confused what I need to choose http://www.userbenchmark.com/PCBuilder/Custom/S67316-M347462.251565.200815.161079.102222vsS59466-M353078.251565.200815.1…
