I own a laptop, which is actually quite powerful.
It can run GTA V using the maximum settings: 1080p30. I'd like to have a triple monitor setup with it, with a true HDMI monitor (I don't have it with me yet, so I can't be very specific as for the model, but it's a Samsung 1080p 60hz ultrawide monitor), and an old television that has a VGA input (yes, I do own the HDMI > VGA Adapter).
Machine: Lenovo Y50-70
CPU: Intel i7-4710HQ, 2.6 GHz, 4 cores, 8 threads
RAM: 12GB
GPU: NVIDIA GeForce GTX860M 4GB Maxwell, Intel HD 4600
OS: Windows 10 Pro
My laptop is soon-to-die, and I am probably gonna build my own laptop around christmas, so not so soon.
