Took me forever to find stock of 4800 with a 2060. I suspect they maybe be short supply of these new ones as well. Even then I couldn't only get it with the ram, hd and battery I wanted. But I can upgrade those later. The majority of laptops I could find in stock were Intel or AMD with 1650. B
But I eventually found one in Jan, so bought it. I need a second one. So I'll wait for the new ones to buy that. I suspect it will well into the summer though to get exactly what I'm looking for. They will probably be a lot more expensive though a 30xx in them.
One thing to look out for is the power rating of the GPU.
