what kind of graphics memory usage are you seeing with your card (I assume you use a program like EVGA Precision, which is what I have, as well as MSI Afterburner.) How often do you get over 2 GB VRAM usage at 1080 P resolution or over 95% graphics card usage?
I play in a 1500x850 windows so I can do other things while running SE, so I don't really use my card much. When I take screens in 1080 I get around 90% use with my graphical settings and around 3GBs in VRAM use, SE seems to offload to system RAM no matter what.
In 4k resolution I can push 100% utilization and around 4 to 5GBs of VRAM use, though with a ton of ships spawned I have pushed 9GBs and crashed shortly after.

You have a multimon set up too, Doc? Your card doesn't heat up past the 80-85C range does it? As long as it doesn't do that, the 90% or higher gpu usage rate isn't harmful to the longterm health of the card? I use SE in a 1024x768 window and get around 98% usage and temps between 80-85C. What kind of usage, gpu temp and gpu memory usage do you get in window mode?
