Looking at the D750 recently. An FX sensor with a menu option to switch to DX. My question may seem obvious but not 100% certain so.......it's a 24.3 MP FX sensor but when you switch to DX is it now a 16.2 MP sensor?
Hi Bruce! Truly a fantastic camera and the sensor is the only reason I've kept my D600 (same sensor, though even better optimized on the D750))...the image quality is simply beautiful and I believe a sweet spot for FX/full-frame sensors. The colour depth and dynamic range is wonderful, and the resolution is, IMO, perfect.
The D750 I believe has two crop options, a 1.2x and 1.5x, the latter of which is equivalent to the DX-sized sensor. If my memory serves me correctly, it's closer to 10MP for the DX crop, but around 16.7MP on the smaller crop.
I don't recall if the fps increases when in crop mode on the D750. If it doesn't, there's very little reason to use the crop modes IMO. One of the only times I've done so or encouraged my kids to do so is on a scene with a cooperative subject (we shoot wildlife) that looks to be a real contender for competition...many comps only permit minimal cropping (despite the huge increase in resolution over the years) from the original file, so this is a way to accomplish that on a scene that needs to be brought closer and it's not possible or ethical for us to physically move closer.
Anyway, probably more of an answer than you asked for, and as I don't own this particular body, you might want to confirm with someone who does or the Nikon website, etc.

Good info...thanks John. I assume then I can use my DX lenses without vignette when in crop mode?

The D750 is an FX camera which can be adjusted to capture a DX image (1.5 crop factor) or an intermediate size (1.2 crop factor). The DX image is 24 x 16mm or 3936 x 2614 pixels giving a 10.3 megapixel image. In the Shooting Menu, under Image Area you can select FX, 1.2 or DX. You can also set the camera to automatically switch to DX mode whenever you attach a DX lens. You will get no vignetting with DX lenses when the camera is set to DX.

I can't really add to what Don and John already posted, but just want to say that the D750 is a great camera. I've had mine for almost a year and am extremely happy with it. I don't often use it in DX mode, but I have one of my custom menu items set for that, which makes it easy and relatively fast to switch modes.
