Game benchmarks with frame-rate scores are deceptive when judging a G-Sync setup (and the same might be said of the AMD version, called FreeSync). In non-game applications, it fell a little behind some laptops with more powerful MX and K-series Core i7 processors, but not by a huge margin. In gaming tests, this new G751 turned in excellent scores, helped by the top-end graphics card and the hefty 24GB of RAM. That's pretty close to the top of the line, although we should expect newer CPUs from Intel's latest Skylake generation sometime later in 2015.
Both have the Intel Core i7-4710HQ CPU and Nvidia GeForce GTX 980M GPU, along with 24GB of RAM and a 256GB SSD/1TB HDD storage combo. This version of the Asus G751 had a very similar configuration to the previous non-G-Sync model we tested in 2014. This is still a premium 17.3-inch gaming laptop that combines a high-end Core i7 CPU, a hefty 24GB of RAM, a big 256GB SSD paired with a 1TB 7,200rpm HDD, and the GeForce 980M GPU. If you've read our review of the previous version of the Asus G751, you'll find that aside from G-Sync support, little has changed.

The big advantage is that you can go into the settings menu of your favorite PC games and turn off the checkbox for "v-sync," shorthand for "vertical synchronization," which can be a big performance drain, even on powerful gaming PCs. But, unless you're very familiar with how PC games look and play under different hardware, the effect is subtle.
In this laptop, as well as on the Origin PC Eon17-X with G-Sync we tried at E3 2015, we saw similarly smooth results. That's because the GPU's output in a G-Sync setup is locked to the refresh rate of the screen, which in this case is 75 frames per second. In the desktop setups we've tested it on, G-Sync has performed impressively, with games looking smoother and faster, even though we we pumping out fewer frames per second, not more.
