We've reviewed a lot of pre-built gaming PCs lately, and although we've found 2 that did well in our challenging test suite, most of them make common mistakes. This video shows that. Sponsor: Get 10% off Squarespace purchases (https://geni.us/BqEpf) Between single-channel RAM configurations, bloatware (preinstalled software), and proprietary parts, we'd have enough to condemn any prebuilt gaming PC -- but there's more still that the worst of the worst manage to screw-up. The ABS Challenger and Skytech systems we tested have both passed our grueling test suite, but with the scattered remains of their adversaries on our lab floor, it's time to recap exactly what it is that the others are doing wrong.
