It looks pretty good and I don't see anything that would be causing audio glitches so it matches what you experienced. Did you use driver version 342.01 for the G210? The latest Nvidia driver is 416.81 but 342.01 is the last version which is compatible with the G210 according to the Nvidia driver download site. The display adapter configuration information seems to be missing for some reason which was true for the trace using the Microsoft driver. The drop in CPU usage would suggest the GPU is doing the graphics work but can you check in Device Manager to make sure it's showing a Nvidia device?
It looks like there were a few more processes running in the GT710 trace but I don't think they would be more than the system could handle. Spotify wasn't running in the G210 trace so less network traffic was going on but I still don't think it would make the difference. I'm going to try and compare the two to see if I can figure out if it's a driver or software issue but I'm still leaning towards the new GPU being defective. I thought it might be a power issue but power requirements should be the same according to the specs.
Please let me know which Nvidia driver you used for each GPU and if you've tried installing only the graphics drivers for the GT710 - meaning selecting Nvidia Graphics Driver (rather than Nvidia Graphics Driver and Geforce Experience), Custom (Advanced), install without installing Geforce Experience, uncheck all of the custom options that can be unchecked, and then selecting Perform a clean installation.
