Just moved and wife convinced me to ditch the pc, any good laptops selling from Costco? Looking to play D2r and maybe D4 if it's any good when it comes out.

Just go to costco and looking at the gpus inside the laptops

Minimum gtx 1650
Maximum rtx 3060b

I wouldnt go higher than a 3060 for d2r and d4. Dont know how the 1650 would hold up in d4. Should be okay.

What's your budget?

My wifes MSI GE76 is relatively nice to game on, it's a 3060 with a Ryzen 7 5800H 17.3" screen @144hz we got on sale online for $1,499.99. Doesn't get very loud and the larger screen is quite nice. Ofcourse if you do some searching I'm sure you can find similar if not better specs for the same price.

Why wouldn’t you go higher than 3060 for d2 and d4? Redundancy?

laptops dont need powerful gpus. you are powering a 17'' screen...

It would make a difference with external monitors though, right?

yes i suppose.
