Laptop review i7

The GT 840m is a mainstream / mid-range graphics chip. It is far better than any integrated graphics core. However, it will not perform as well as a higher end graphics chip. Typically most people would say that the GTX 850m is the lowest graphics chip that is considered a "gaming graphics chip".

The greater the resolution you want to play a game at, the more powerful graphics chip you will need. The GT 840m is capable of playing most current games on medium settings @ 1366x768. However, at 1080p resolution you are looking at low settings for most games except the ones with low graphic requirements.
