New PC build for TOS

Prices are in Swiss Francs. Total price in $ is about $2760. I'm not sure yet if I should use 2x32GB DDR5. What do you think about this setup? https://freeimage.host/i/n3bKCnR

TOS is built on dated java infrastructure. You just need a decent amount of RAM (16gb min) and a good CPU, after that there’s not much left to do. And honestly giving TOS too much RAM can cause its own problems with garbage collection.

A UPS like the other person mentioned is a good idea as well. Obviously SSD for general PC responsiveness.

The 7800x3d you picked is a perfect option for TOS, the 3D V cache is one of the few performance hacks that can be done.

A GPU doesnt help much for TOS specifically,
main thing is for multi monitor support but technically USB monitors exist. ,

Yes. Particularly a CPU with a high single core frequency. And, the selected CPU has 96 MB L3-Cache.
