Nvidia 650m 512mb vram gaming?

At that resolution it should be fine. Most modern games will run fine with that much of Vram, though i can't say with high end games like Skyrim, rage, etc. on windows

using an external screen up to 1080p though might have issues.

This video is a prime example of a game that uses high quality textures with low vram

Also, if you are using parallel or vmware, that will chew more on the vram, not recommended.

Ya at that res it should be fine. But don't expect every game to run at high settings. Some games are much more demanding than others.
