Gaming-Focused: Alienware M17x R4
You’ll be hard-pressed to find a gaming laptop with more power than the Alienware M17x R4, which is loaded with one of the most powerful Ivy Bridge processors available.
On top of the third-generation Intel Core i7-3720QM processor, the M17x R4 also packs an Nvidia GeForce GTX 880M discrete graphics card for smooth gaming performance, RAM upgradable to 32GB, and hard-drive space starting at 500GB.
Even with all that power, the battery lives on: In PCWorld Labs tests, it lasted close to 5.5 hours.
