Before I Ask for Budget Approval to Build a Top-Notch Server for AG, I need some info...

We have a CPU issue in the Dolby Atmos mastering room at thew studio. We've been due to replace the PC, but have been stuck trying to decide whether we need to build around the latest version of the CPU in the old PC that's overdue for replacement or go with a Threadripper Pro.

OLD PC: Ryzen9 5950X, 128GB DDR4, Red Dragon RX6800, Marian ClaraE 512x512 channel Dante PCIe.

THE ISSUE: Adding 4 or more 7.1.2/ 7.1.4/ 9.1.6/ 3OA ambisonic reverb/delay plugins cause CPU overload. They're essential tools for our work, so we need a solution. I wanted to go with a 96-core TRxPro and 2TB DDR5 and be done with worrying about the computer for awhile, but Task Manager is always below 50% when the overload happens. Typically around 24-32%. So, I'm thinking that means FabFilter Pro-R2, LiquidSonics Seventh Heaven, etc. like to eat up a single core whenever used in 7.1.2 and higher channel-widths.

If its a single-core issue, a 9950X would be our best bet, but the difference isn't big enough between it and the 5950X to make up the big difference we're looking for and I'd really like to add more cores for other plugins, side-chain routing, etc. So, the best solution appears to be for us to build a new main PC for the Atmos room on a TRx-Pro, and build at least a pair of AG servers around the Ryzen9 9950X. That way, we can run as much of whatever we want in Nuendo13 (our main DAW) with advanced processing of clients' tracks in SpectraLayers Pro11, WaveLabPro12, analog processing, and however many plugins a project needs all within Nuendo without worrying about limitations, and then the AG servers can mostly be there just to handle those immersive sized channels.
 

1. Does AG work for multichannel plugins, including 5.1, 7.1, 7.1.2, 9.1.6, and even 3OA, or just mono and stereo?

2. Any recommendations?

3. Any issues I may need to worry about?
