Bolton, UK-based Scan's latest machine uses the new AMD Radeon RX 480, which is one of the market's best mid-range cards, and the GPU is paired with an overclocked Core i5 processor. Scan reckons it's ideal for 1080p and 1440p gaming, and we're loathe to disagree. The 3XS Z170 Performance GTK4 starts at $1,444 (about £1,090, AU$1,907).Gloss dropThe GTK4 is built inside the pleasing NZXT Source 340 chassis. Its front is a solid slab of glossy black metal, and its roof and rear panel are similarly subtle. The main side panel is decorated with a huge window. Build quality is reassuring, and there's not much size difference between the Scan and the Overclockers Titan Virtual Force ? the latter system is only a few centimetres bigger.
