I was having the same hour long default training times so I picked up a PNY GeForce GTX 1650 at Best Buy for $179
Win 10
I9 10 core 10850K
16G Ram
GTX 1650 running the default NVIDIA driver that Windows installed automatically V 30.0.15.1215.
Default Training under 3 min usually ~2:50
Advanced Training Under 20 min ~19:15
These are real close (even better) times that some are reporting with $530+ RTX 3070s.
A few things of note: I do not have any monitors hooked up to the 1650 yet so it is just really being used for ToneX. Video is through a Dell D6000 USB docking station. Also, the 1650 runs pretty quiet. I thought that the two fans on it might cause a noise issue but it turned out to be a non issue.
FWIW, I also did a capture on a MacBook air M1 (7 core GPU) w/8g Ram and Default Training took about 15 Min.
Hope this helps.
