for ue4 that is more than enough.
issues with high end gaming laptops is that they always push the limits and some time they may fail miserable.
you should keep track of what people are saying about a particular model.
I’ve had an Asus gaming laptop a few years ago, which failed a few months out of warranty with no way for me to fix it. The budget to repair it was like 40% of the price of a new, way better specs, gaming laptop. So I’ve bought that instead. not Asus off course, I will not touch them again.
If possible, if you don’t need the power on the go, best to get a normal PC build, if something breaks, you can replace it without too much trouble, you can even upgrade it down the line.
