Let’s start with that GeForce GTX 970M under the G752VT-DH72’s hood. Though obviously not the fastest discrete module available, Asus connects it to a 17.3” IPS panel with G-Sync support and a 75Hz refresh rate. So, even when the GPU can’t maintain 75 FPS, synchronization in the display subsystem keeps the output smooth. Once you spend time in front of G-Sync (or FreeSync), it’s hard not to notice the artifacts associated with turning v-sync on or off. Particularly at 1920x1080, the technology lets you get away with a less powerful graphics module, ultimately saving some money. The rest of the platform falls into place nicely. Intel’s Core i7-6700HQ operates at a modest 2.6GHz and only includes 6MB of shared L3 cache. But the quad-core CPU is still a screamer (even if we would have preferred the -6820HQ, which Intel claims is similarly-priced). Sixteen gigabytes of DDR4-2133 memory split across two SO-DIMM slots are fairly standard. If you find yourself needing more, a panel on the chassis’ undercarriage pops off to reveal a pair of vacant slots.
Asus smartly built a tiered storage subsystem consisting of Samsung’s 128GB PM951 and a 1TB HGST Travelstar. The SSD, equipped with triple-level-cell NAND, is nowhere near as fast as the flagship SM951. However, it does communicate over a four-lane PCIe link using NVMe. Asus offers another configuration with a 256GB SSD and 24GB of RAM for an extra $200, but enthusiasts looking for more capacity can manually upgrade the 128GB version too (the aforementioned panel also reveals an empty M.2 2280 slot).We certainly get what Asus is trying to do here. By keeping the G752VT-DH72’s SSD small, yet functional, and its graphics powerful, but not overkill, the company can sell this thing for about $1,650. Six other systems in our round-up cost more. Plugged into the wall, G-Sync keeps the action enjoyable. Away from it, Nvidia’s Battery Boost technology throttles you back to 30 FPS by default. Just don’t expect a ton of game time on the road. Our loop of Unigine Valley at 1920x1080 only lasted 43 minutes before the G752VT-DH72 shut itself off, landing in last place.
A somewhat meager battery is but one compromise you make in going the budget route. Asus hasn’t done much to improve its audio over the last Republic of Gamers notebook we reviewed, either. High frequencies lack crispness, while lows sound muddled. Tweaking around in the Sonic Studio II app helps, but you’re going to want a good headset.I’m also not a fan of the updated chassis; it employs more angles, less soft-touch material, and a brushed silver/copper color scheme. Fortunately, none of the surfaces attract finger oils. The top panel does flex quite a bit, and our sample had noticeable gaps between the screen and bezel. There is a smoked plastic window across the undercarriage, which gives you a nice view of Asus’ cooling solution. However, it was already pretty scratched up on the unit we received.Though several of the G752VT-DH72’s competitors serve up more peripheral connectivity, we didn’t feel like we were missing anything crucial. Gigabit Ethernet, HDMI, mini-DisplayPort 1.2, four USB 3.0 ports, one USB 3.1 Type C port with Thunderbolt 3 support, digital and analog audio I/O, an SD card reader, and a dual-layer DVD±R/RW drive cover the bases well. You also get a built-in Intel Dual-Band Wireless-AC 7265 adapter with Bluetooth 4.0, plus an integrated 1.2 megapixel webcam.
Naturally, gamers will want to use the G752VT-DH72 with their own mice. But the oversized trackpad suffices in productivity apps. Its right- and left-click buttons have just the right amount of travel and depress uniformly. We prefer this to buttons that are raised on one side. Asus’ keyboard is similarly executed well, though its red backlight doesn’t match the new silver/copper color scheme as well as the old black/red design. Function keys along the top make it easy to adjust backlight intensity, disable the trackpad, switch display outputs, or put the notebook to sleep.Despite our smattering of critiques, the bottom line is that Asus’ G752VT-DH72 delivers smooth gaming performance at an impressive $1,650 price point. G-Sync technology, a GeForce GTX 970M, the SM951 SSD, and Intel’s Skylake architecture come together in a package that Goldilocks would call “just right.”
Given the efficiency of today’s CPUs and GPUs, it’s easy to build a gaming notebook capable of displacing high-end desktops. Alright, “easy” marginalizes the task a bit. But enterprising OEMs certainly fit gobs of performance into the power budget of a mobile platform. The bigger challenge is crafting a laptop that’s so comfortable to use, enthusiasts don’t mind kissing their desktop PCs goodbye. Of the systems in our round-up, MSI’s GT72S Dominator Pro G 29th Anniversary Edition comes closest to compelling us.Make no mistake, the competition in this segment is stiff. Alienware sent in its 17 R3 with a 4K panel and Graphics Amplifier—an external housing that takes an add-in graphics card for unmatched performance. Sager shipped its NP9870-S (effectively the same as a Clevo P870DM) sporting Intel’s desktop Core i7-6700K processor and a GeForce GTX 980 with 8GB of memory. MSI differentiates with stylish looks, solid audio, expandability, and a keyboard we wouldn’t mind using for extended gaming sessions, plus its own selection of high-end hardware.

Like Alienware, MSI leans on Intel’s Core i7-6820HK, the only Skylake-H processor with an unlocked multiplier. The notebook’s Shift technology is supposed to facilitate dynamic overclocking from within Windows, but our tests didn’t reveal any difference between the standard Comfort mode and Sport. Fortunately, you do get access to clock rate and voltage controls through the UEFI. Five profile slots store favorite configurations for use later.A 2.7GHz base frequency and 3.6GHz peak Turbo Boost mode keep the quad-core CPU spritely in most workloads, even without overclocking. You’re much more likely to run out of graphics horsepower in a modern game. To combat this, MSI deploys Nvidia’s fastest mobile solution, the GeForce GTX 980—a near facsimile of the desktop GTX 980. Both employ a fully-enabled GM204 with 2048 CUDA cores. And while official specifications list the laptop-bound version at slightly lower clock rates, the GT72S’s cooling is good enough to allow GPU Boost speeds in excess of the add-in board.You might say the 980 is overkill for a 17.3” screen at 1920x1080, and indeed its average frame rates typically exceed the 75Hz display’s native refresh. But we’d point out that MSI’s specs do satisfy the minimum requirement for Oculus’ Rift headset. And when you’re not immersed in virtual reality, it’s hard to complain about G-Sync support on an IPS panel.
It’s also easy to fall in love with the two 128GB Samsung SM951s that MSI stripes together in RAID 0. Individually, those PCIe-based SSDs are capable of 2GB/s sequential reads and up to 650MB/s sequential writes, so you’re looking at incredible storage performance. Unfortunately, the two vacant M.2 slots under the hood cannot be populated with SATA drives, so long as the PCIe SSDs are installed. Should you fill up the SM951s and 1TB HGST Travelstar, you’ll have to start swapping in larger drives. MSI does populate all four of its memory slots—this configuration includes 32GB of DDR4-2133. We don’t think you’ll mind the lack of available expansion there.Nobody expects a desktop replacement to do its business away from a wall socket, but the GT72S Dominator Pro does last almost 10 minutes longer than Asus’ G752VT-DH72 in our Unigine Valley loop. Of course, the massive nine-cell power source also adds considerable weight—we measured the notebook at 3.90kg (versus MSI’s 3.78kg specification). For comparison, Alienware’s 17 R3 is a little lighter at 3.68kg, while Sager’s NP9870-S tips the scale at 5.00kg.
Whereas MSI keeps the GT72S’s heft under control, the company gets fairly flamboyant in the aesthetics department. You’re either going to love or hate the red cover with its dragon profile and LED-lit eye. The dragon makes its return on the palm rest, though your eyes will probably be diverted by the full-color backlit keyboard. Unfortunately, the driver on our review unit wouldn’t load, but we’re plenty familiar with SteelSeries’ technology and the comfortable island-style layout.A larger chassis means more room for peripheral connectivity. You get six USB 3.0 ports, one USB 3.1 Type C port with Thunderbolt 3, audio I/O, an SD card reader, gigabit Ethernet, HDMI 1.4, mini-DisplayPort 1.2, and a Blu-ray writer (a built-in Killer Wireless card covers 802.11ac networking as well). The roomy enclosure also leaves plenty of room for cooling. By default, the GT72S idles along quietly, spinning up only when you hit it with a gaming load. We never found it necessary to activate the keyboard’s fan boost button; maximum performance was easily achievable out of the box.

Plenty of desktop replacements tantalize with more exotic specifications, but MSI’s GT72S Dominator Pro G 29th Anniversary Edition gets us great gaming performance, plenty of power for productivity apps, ample connectivity, reasonable upgradeability, and a fair price.
