I have a Rog Strix 17 Inch size, 2 years old, with 1050 NVidia, 4 Meg of Video Ram......Converted with 2 SSD's one is a M-2......Way better than Platter Drives.....Day is to night difference.......16 Meg maxed out for this model......
Some laptops come with 6-8 Meg on Video Card, but then, your Battery will be eaten up by power usage and heat buildup, so your mileage will vary.......Mine being 4 Megs and my first dedicated Video Card, NOT INTEGRATED EITHER is your best option....My old HP was INTEGRATED ON MOTHER BOARD, and a piece of !@#$%T$ in performance, because 5 years ago, I didn't know better....I sure do now.......Love my NVIDIA card.......
U also need to know, you cannot in most Laptops upgrade your Video Card, so it is very important you choose best size of NVidia Card for your needs, balanced with power requirements and Heat impacts......
Would suggest for WaddleDee18 add one accessory that has made a world of difference for cooling one's Laptop......
Cooling Pad

Now just the fact it
elevates your Laptop at 1-2 inches on one end, allows more cool air to get underneath where heat builds and gets trapped Etc.....I used to use a 14 and 15inch Laptops, and Real Estate for Screen Size makes a huge difference, at least for me, I am older person, so like others here, the eyes need all the help they can get....With that thought, larger the Laptop more weight to lug around.....So it is assumed a Balance between size and visual needs requires a compromise, what is best for you.........
In summer I turn the fans on, in Winter, very occasional, because the house temps are cooler by 30-40 degrees over Summer Heat in Southern California........
I almost burned my Laptop up with Trainz, and dirty internal fans, which I had to blow the Dust Bunnies out of it.......
It is Quite normal for Laptops, which need Air Duct Cleaning at least once a year with Air Cans............
Don't use an Air Hose or you will damage something inside your Laptop...
