Test Setup

Our GPU test rig uses Intel's X99 platform. Specifically, we use the Asus Rampage V Extreme paired with an Intel Core i7-5960X. This combination gives us 40 PCI-E 3.0 lanes to play with, meaning that even if we test 4-way SLI set-ups, we'll have available the maximum possible bandwidth. With eight cores and 16 threads via HyperThreading, the CPU ensures even the most multi-threaded games won't be bottlenecked, and we've overclocked it to 4.2GHz as well with a baseclock of 127.3MHz, a multiplier of 33 and a vcore of 1.25V, further alleviating CPU bottlenecks. The CPU is paired with 16GB (4 x 4GB) of Corsair Vengeance LPX DDR4 clocked at 2,667MHz and cooled by a Corsair Hydro Series H75.

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 4-way set-ups with 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. We typically use FRAPS to record the average and minimum frame rates, but may use a game's own benchmark measurement tools in the event FRAPS doesn't work (e.g. with certain DX12 titles). 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.
