hi, not sure if you've bought the laptop yet but I would strongly recommend getting either a RTX 3060 or preferably 3070. They offer significant improvements over the 20** series cards.
Depending on your budget and location, there are quite a few laptops being released at the end of this month that you should really consider. If you need more info, just ask 
I work for an architectural practice here in the UK and we've been using Enscape for a while now. Last week, I shared my screen over a Microsoft Teams call with the Head of Planning for a Council and they were blown away by the Enscape presentation. The ability to 'walk' them through the scheme helped sell the scheme.
Where we've run into problems as an practice is in VR presentations to councils. There are a number of issues that I we've come across
1 - carrying the PC, VR headset and all the cables, keyboard etc to meetings (laptops not powerful enough for size of model etc)
2 - setting up PC and VR headset in front of clients/council
3 - quality of Enscape render. The 'shimmer' on objects and materials in enscape VR is a major issue. It detracts from the experience and caused users to feel dizzy at times.
The new Oculus Quest 2 might be a solution for the first two points. If there is a way to open a fully pre-rendered file on the Quest 2 that might do the trick.
Is point 3 regarding the 'shimmer' something currently being worked on?
