I don’t know how the P5000 compete with the gamer market GFX1080 ti (which are good choices for RC).I would definitely add much more storage… You never have enough with RC (the cache fills up very quickly)… Take at least 3x2TB SSD. Put the cache on one of them and the projects on the others. 128GB RAM sounds like something reasonable.
Thank you Jonathan. We are going for an EVO PRO NVME 2 TB as you suggested. Addition SSDs will be put, as well as a NAS 14TB for backup for all the workstations in the office.
What troubles me is the 3-way graphics Cards. Maybe some input from admins and other users could be very helpful.
You should consider a CPU with a lot of threads. 90% of the processing time is on the CPU, you could use one quadro and use the rest of the budget on a great CPU.
