I will definitely try this. Currently at default settings. I made this render in 2 hours. I made this render in 10 hours on my old computer. I'm really happy with the GPU performance right now.

These are some I done with my 1050TI. I set the denoising to 200 iterations, to denoise on the last iteration. I turn off quality to ensure that it only goes to 200 iterations (set the max to 200 in the performance settings) and it took 5-10 mins (usually close to 5 mins) and looks fine. Of course, you can experiment with how many iterations you're comfortable with, you may like more and be okay with waiting longer. What I did was I created a bunch of renders using the same image and just changed the iterations for each render then I compared the renders to see which looked best and whether more iterations were worth waiting for, in my case, I didn't feel like waiting a long time for very little difference...
I was the most proud of this next one as I managed to fit three characters in my measly 4G of VRAM. I had to hide A LOT of geometry to get it to render. You can also use scripts like the Scene Optimizer to reduce the texture size so it will fit on your video card, that combined with hiding geometry helps a lot...
To give you an idea of what I mean by hiding geometry, this next image was one I created back then and shows this scene from my Daz Studio view and you can see Liam in the door isn't quit "all there"... heheh... most of his body is gone (clicked each part not visible in the render and click the EYE icon to hide it as hidden geometry is not loaded into the VRAM at render time). Also note that most of the bathroom which is not visible has been hidden...
