If I upgraded to an I9 with an Nvida 4090, would render times drop dramatically?

Cool render.

A 4090 is far faster than any GTX card, by about 3.5 times in most benchmarks that render. RTX cards can also render in Optix, which can be much faster than CUDA.

Exactly how much faster really depends on what your rendering thou.

I have a 2060 in this system and want to get a 4060ti 16 gig card to render when they come out, just for the memory capacity and the speed it will render in Optix. GPU memory is a bit more important to me than going all the way to a 4090 for the speed advantage that draws 400+ watts and runs me out of the room from the heat output.

You also don't need an I9 to do GPU renders. I went with an I5 13600k processor for the power savings. It has 20 threads and sitting here typing to you the processor is using very little power jumping between 6 and 15 watts. I and drops to 4.3ghtz under full load of about 170 watts.  If you do cpu intensive stuff an I9 is a great processor, but it is also a power hog. 

Speed is great if you need it all the time. But it costs far more to run it in the long run.
