I am currently looking to buy a gaming laptops that could run graphics-intense games like Witcher 3 and Battlefield..I found a laptop with the following specs. My question is: Is this adequate?
4th Generation Intel® Core™ i7-4710HQ Processor (6M Cache, up to 3.50 GHz)
8GB Dual Channel DDR3L 1600MHz (4GBx2)
1TB 5400 rpm SATA Hybrid Hard Drive with 8GB Cache
NVIDIA® GeForce® GTX 850M 4GB DDR3
Notebookcheck is a great site for seeing how games will run with a particular mobile GPU. Scroll down to their page for the 850m and you will see the fps they got with a variety of games across a bunch of different laptops with the 850m.
Note that the particular laptop you've chosen has the 850m with DDR3. The 850m can be coupled with either DDR3 or DDR5. So your expected framerate will not be towards the high end that notebookcheck lists.
