Firstly I should add my current lenses. Nikon AF-S DX 18-140mm F3.5-5.6G ED VR, Nikon AF-S 50mm F1.8G, Nikon AF-S DX Micro 85mm F3.5G ED VR, Nikon AF-S VR 70-300mm F4.5-5.6G IF.
I will give an example of recently when I thought I needed better low light performance. I just got back from Florida but while there last week the wife and I went for a walk along a boardwalk through a mangrove forest. The overhead canopy was thick and only let minimal light through. I was using the Nikon 18-140mm F3.5-5.6 lens and found that I was using it at 18mm and right up to the full available zoom depending on what I was shooting. I couldn't leave the boardwalk to get closer to a subject for fear of crocs and water depth.
After ready the replies to my post here it got me to thinking about a different way to possibly approach my concern. First I thought I could trade in my D7100 for a D7200 which has better high ISO performance but this would be expensive for what little improvement I would get. Then as I took a second look at the images I took in FL I realized I'm very stingy on upping my ISO. I use manual ISO and usually shoot between ISO 100 to 400. Only occasionally going as high as 800. I did some research and found that the D7100 has given many people acceptable images at up to ISO 1600. Acceptable being different for different people of course.
So should I experiment shooting at higher ISO's in low light conditions to see if I'm happy with the result? This would allow for faster shutter speeds and more flexibility in choosing an aperture. Thinking out loud here.
