ASUS ROG G20AJ

Graphics & Performance

The mainstream configuration of the G20AJ is built around a solid suite of components, including a 3.6GHz Intel Core i7-4790 processor, an NVIDIA GeForce GTX 760 and 16GB of memory. In benchmarking from our colleagues at Tom's Hardware, the GTX 760 showed its bona fides as a reliable mainstream graphics card.

At a resolution of 1920 x 1080 and high quality settings, the card produced an average frame rate of 49 frames per second (fps) while running "Battlefield 4." Using older titles like "Tomb Raider" and "Far Cry 3," the card produced respective frame rates of 78 and 67 fps. For most situations, the card has the necessary processing overhead to handle current PC gaming titles in standard 1920 x 1080 high definition. Still, more demanding users can switch to one of G20AJ's faster configurations built with NVIDIA's GTX 700 series of graphics cards. Available graphics cards include the higher-end NVIDIA GeForce GTX 780 and entry-level GT 750.

Processor & Storage

The ASUS pairs its NVIDIA graphics card with equally reliable fourth-generation Haswell Intel Core series processors. These aren't the most current processors offered by the manufacturer, as Haswell has since been superseded by Intel's Broadwell series of processors. Still, the mainstream G20AJ's Intel Core i7 processor produced excellent scores in synthetic benchmarking from our colleagues at Anandtech. In day-to-day use, the Core i7 is able to handle gaming or high-demand applications like video compression or image editing without suffering from significant performance issues.

If you're a more budget-minded user, alternative G20AJ setups use an Intel Core i3 and Core i5 processor. In addition, storage options include hard disk drives of up to 3TB and solid-state drives with up to 256GB of space. While exact hard drive options depend on your specific G20AJ configuration, solid-state and hard-disk drives are both useful additions for a demanding gaming PC. High-capacity drives allow you to store files

Design & Connectivity

With a look that's a cross between a small form-factor gaming desktop computer and a gadget from "Guardians of the Galaxy," the G20AJ's appearance is undeniably distinctive. The arched plastic black siding on the computer feels durably constructed and hides a handful of areas for circulating hot air.

The middle of the case discreetly hosts several connectivity options, including USB 3.0 ports, a headphone jack and an optional thin Blu-ray drive. The back of the computer has a full slate of additional ports, including 7.1 audio, six USB ports and display output from the graphics card. With dimensions of only 14.1 x 4.1 x 13.4 inches, the computer is also impressively compact and can fit into a TV stand or desk space with ease.

Like many mass-market gaming PCs, the G20AJ is frequently found in preassembled configurations. While these builds are optimized for various price points, the gaming PC's relatively closed off nature can make it problematic if you want to fine tune details like the computer's memory or hard drive options. Similarly, the ROG relies on an unusually large two-brick style adapter for power. While the plugs' compact build saves space on the case design, the ROG does require two separate power plugs in order to run, making for extra cable clutter.

Help & Support

By default, ASUS includes a one-year warranty on the ROG. Support channels include troubleshooting via phone, email, live chat and a support section on ASUS' website. These product-specific troubleshooting pages have some navigability issues – the G20AJ page has only 10 troubleshooting entries – but still hosts valuable resources, including driver downloads and manuals.
