A:AnswerThe Cyborg 15 A12VE-046US is equipped with an NVIDIA® GeForce RTX™ 4050 Laptop GPU with up to 1605MHz Boost Clock 40W Maximum Graphics Power with Dynamic Boost.
A:AnswerDon't choose an 8GB one. If you run two or more software, it will lag. I installed an 8GB memory module myself and the situation improved a bit.
As for the rest, I cannot provide any suggestions at the moment
A:AnswerAbout 2 hours if not using the GPU. So, basic computing like web browsing, editing documents, etc. Playing Guild Wars 2, I can MAYBE get an hour, if I use best performance and low battery use profile (so no cooler boost).
