Yes.

I also like to put in at least a minimum "gaming" video card for speed and memory, as compared to a more typical office spec.

Unlike Word or Excel, these Intuit programs do not load into memory and stay resident. You can't open multiple iterations. They are making live updates to the database files. This also is why an office should be hardwired and not WiFi LAN.

There are people here who seem to have adequate system specs and still get the "other process is busy" type of message. I've found Intuit doesn't release memory very well.
