Slow Performance Help

Hello,

Looking for some help on my performance. I'm currently using a HP Workstation with 256 RAM, 16.4 TB internal storage, and a 24 GB Graphics Card. The rest of the info is below. I'm frusterating at the amount of lag and slow overall performance. I stay up-to-date on my PC updates and still can't figure out why there is such lag. Is it my graphics card? I have a 49" 5k monitor (which I'm going to change out soon because I'm not a huge fan) but is that screwing things up? Any help is appreciated. 

Computer Specs:

Processor Intel(R) Xeon(R) Gold 5120 CPU @ 2.20GHz 2.19 GHz (2 processors)

Graphics Card NVIDIA QUADRO P6000 24 GB
Installed RAM 256 GB (256 GB usable)
System type 64-bit operating system, x64-based processor
Windows 11 Pro for Workstations
