I'm a bit out of my depth with the combination of that nvidia card and that Intel processor. I'm not sure how the drivers will interact with each other or how it would help or hinder MEP or VPX. Maybe John EB will have a better understanding. As for ram, technically it has twice as much as you would possibly need for 4K but there is no harm in having the extra ram. As it's a laptop the type of screen being offered may also be of interest when considering whatever price is being asked for and battery life.
This spec will handle 4K easily with the proviso that the Intel GPU can be used in combination with the GTX 1650 Ti - see below in the section referring to battery life.
What make/model is the laptop?
The processor and disc size are good, and the GTX 1650 Ti is a good graphics chip. The 64GB RAM is overkill - 32Gb is more than sufficient and the screen size/resolution is not practical as has been mentioned before.
A 15" screen with a resolution of 3840 x 2800 resolution is going to result in VPX icons, text etc being to be small and eye strain is a possibility. You could turn on Windows scaling, however this is, in effect, going to reduce the screen space available to work in.
@CubeAce mentioned battery life - this is something you should bear in mind with respect to run time and performance if you are away from a power source.
The run time on battery alone is going to be shorter, possibly significantly, when VPX uses the GTX for preview rendering, or during exporting when it is used for acceleration of some effects, or encoding if exporting as HEVC (h.265), or performance will drop if the GTX drops into a lower power mode.
If the Intel iGPU is available, this will be used for the encoding and give a better battery runtime as its power consumption is lower, however if the iGPU is not available then the CPU will be encoding and the power consumption will go up, again shortening battery run time.
Thank you. Really helpful. I am looking at the DELL XPS 15 9500. But it is reburbished and only has a one-year warranty. But I am going to think about it,
Good make the only downside I found is when I contacted them re the Intel iGPU availability - they would only answer the question if I had one already - not the best of sales advice when spending so much money.
