Conclusions
There's a lot to like about the way Nvidia's GTX 1070 slots into Gigabyte's P57X. While this GeForce GTX 1070-equipped laptop didn't quite match up to the gaming prowess of our desktop test rig, it came darn close at times. We figured we were being completely unfair to the P57X by pitting it against a hulking desktop, but it surprised us by delivering gaming experiences that hang right with desktop-class parts in a relatively thin and portable chassis. That's an impressive advance in mobile gaming performance by any measure.

We can't let Nvidia steal all of the accolades here, though. In the P57X, Gigabyte delivered a well-planned implementation of the GTX 1070. The machine generally provides around 60 FPS at 1920x1080 in modern games with very high settings. That's a tempting proposition, especially considering that buyers can take it with them on business trips or have it sit on their lap in the living room. The P57X is a bit noisier than we'd like, but it's hard to fault Gigabyte for prioritizing gaming performance and heat dissipation over a little fan noise.

So how well does Gigabyte's P57X match up against the competition? To the extent that style matters, we think that Gigabyte does an excellent job of making laptops that aren't garish embarrasssments. The P57X looks like a professional's computer, and that's worth a lot in today's RGB LED-crazed PC hardware market.

We also like that the P57X offers a flexible and expandable storage system. A modern system should come with a substantially-sized SSD, but it doesn't take long on Newegg to find "gaming" laptops that rely on mechanical spinners alone for their storage. The P57X's stock SATA M.2 SSD and 1TB hard drive are serviceable enough, and folks who want to add more storage can easily do so. (As an aside, we're increasingly of the opinion that 512GB is the right size for a system drive. Our testing suite absolutely crushes 256GB drives. Doom consumes nearly 72GB of space all by itself.)

In this era of retina displays, some might look askance at the P57X's 1920x1080 screen. Given our benchmarking results, however, this resolution looks like a great fit for the mobile GTX 1070. A higher-resolution display would provide a better text-reading experience, but our work with the GTX 1060 and 1070 suggests that users would have to give up a decent amount of gaming performance for those extra pixels if they wanted to game at native resolutions. Higher-resolution screens can also have a negative impact on battery life. Given those constraints, we think Gigabyte made the right choice here.

For about $2000 at retail, Gigabyte has priced the P57X v6 right in line with many other GTX 1070-equipped laptops. If a 17.3" notebook fits your lifestyle (and backpack), we think the P57X v6 is a solid example of the breed that can deliver true desktop-class performance in a portable package. It's well worth a look if you demand gaming power on the go. We're happy to call it TR Recommended.
