I have Dell G3 3579 with a specs of i5 8th Gen, 4gb RAM and GTX 1050. I am wondering if they would sell/upgrade my laptop with GTX 1050ti or higher since they also released it on the same G3 3579.
PS Sorry for my noobness
Welcome to the Dell Community @3579 newbie
Since the GPU is discrete it cannot be upgraded.
You would have to purchase a new system board to upgrade.
With the cost it would be better to purchase a new system with the requirements you need.
