But as I said earlier, most games are GPU bound, and the Predator has a faster video card (one based on Nvidia's GeForce GTX 770). Now look at the two machines' gaming benchmarks. With resolution at 2560x1600 and image quality at ultra, Battlefield 4 ran at 30.45 frames per second on the Lenovo versus 31.45 frames per second on Acer's machine.
One frame per second isn't a huge difference, but the delta widens when you go down to the resolutions you'll more likely be gaming at with a 24-inch monitor: With resolution at 1920x1080 and image quality at medium, the Predator pumps out 146.5 frames per second to the Erazer's 125.5. BioShock: Infinite tells the same tale: 153.6 fps for the Predator versus 119.1 fps on the Erazer (here again, with 1920x1080 resolution and medium image quality).
That's not to say Lenovo built a weak machine--the Erazer delivers very good performance for the price--it's just that the Predator is a better gaming machine for the money, despite having a lesser CPU and half as much memory.
The Erazer X510's steel case design is much like the rest of Lenovo's gaming lineup: It's sleek, black, and angular, with understated LED accents up front. A hidden door on the top of the case slides open to reveal the power button, two USB 3.0 ports (one of which remains powered as long as the PC is plugged in, so you can charge your smartphone or tablet), a memory card reader, mic and headphone jacks, and a button that turns the LEDs off. A hinged door conceals a tray-loading DVD burner, the aforementioned hot-swappable drive bay, and a 5.25-inch bay.
Lenovo's cooling strategy is weak, however; there are just two case fans and there are no convenient locations to mount aftermarket fans. You'll want to take care to keep those two fans--and the case in general--free from dust accumulations that could cause the system to overheat, especially if you're running it overclocked all the time.
Should you buy one?
The Erazer X510 is a middle-of-the-road computer for people who want a moderately-powerful machine without the hassle of building one from scratch. Lenovo's component choices render it better suited to productivity and content-creation tasks than gaming (because of its overclocked CPU, but mediocre GPU), but that's okay, because the Erazer X510 carries an appropriately middle-of-the-road price tag.
