GeForce GTX 870M 6GB Game Requirement Analysis
GeForce GTX 870M 6GB is variant of the high-end mobile graphics card - GeForce GTX 870M 3GB.
In this edition, the frame buffer was doubled to 6GB which will not boost its performance and can be addressed as a gimmick - marketing to lure consumers into paying more for the same product.
Thus, its performance is exactly like the 3GB variant.
GeForce GTX 870M 6GB will only be seen on large notebooks and it needs to be paired with 8GB of RAM and a Strong Quad Core. The card is suited for 1080p and even the most demanding games should run fluently at high settings.
