Schematics and such for electronics so my minimum standard is the usual i7 CPU, 16GB RAM, 1050 Ti or better GPU and an external 4K display of as big as you like. It won't match the speed of a desktop GPU but it's not expensive and works well.
Currently on an Acer Predator and prior was an Asus ROG. Both just above 1K USD.
Now if you want to have these with the "workstation" cred and Nvidia Quadro or Tesla GPUs you can double that price. I'm too cheap and have used gamer laptops for this for decades now. I won't pay workstation prices.
I currently have a MacBook but was considering switching over to PC for software compatibility reasons.
My budget is $2500
I need a laptop that I can be reviewing blueprints while working in excel and a takeoff program on multiple monitors. Any suggestions on a route I should take for a laptop?
