Our GPU test rig uses Intel's Z170 platform. Specifically, we use the Asus ROG Maximus VIII Hero Alpha
paired with an Intel Core i7-6700K
. With four cores and eight threads via HyperThreading, the CPU ensures even the most multi-threaded games won't be bottlenecked, and we've overclocked it to 4.5GHz as well with a base clock of 100MHz, a multiplier of 45 and a vcore of 1.28V, further alleviating CPU bottlenecks. The CPU is paired with 16GB (4 x 4GB) of Corsair Vengeance LPX DDR4 clocked at 3,000MHz and cooled by a Corsair Hydro Series H100i GTX
The rig is powered by the Corsair AX1500i, which has enough wattage and 8-pin PCI-E power connectors to deal with any multi-GPU set-up we care to throw at it. It's all housed inside a Corsair Graphite Series 760T
, which is spacious enough for any card. The final component is an OCZ Vector 180
960GB SSD, giving us plenty of space for game installs.
Our results come from a mix of built-in benchmarks and custom, manually played sections, depending on the game. All benchmarks are repeated at least three times to ensure consistency. We test at 1,920 x 1,080 (1080p) and 2,560 x 1,440 (1440p), as well as at 3,840 x 2,160 (4K) with higher end cards. The operating system is an up-to-date copy of Windows 10 64-bit.
