Our GPU test rig is equipped with the multi-GPU powerhouse that is the Asus Maximus V Extreme, allowing us to run up to 4-card SLI and CrossFire with 8x PCI-E 3.0 lanes per card. The CPU is an Intel Core i5 3570K running at 4.2GHz to raise the CPU headroom, and it's paired with 8GB of 2,400MHz Corsair Dominator DDR3. Our chassis of choice is NZXT's Switch 810, a case big enough to house even a pair of Asus' Ares 2 graphics cards. The Lepa G1600 1600W PSU offers more wattage and 8-pin PCI-E power connectors than we'd ever need.
To Benchmark Battlefield 4, we're using a 60 second recording of the opening sequence of the campaign's sixth level, Tashgar. It's a very demanding section, as it's fast-paced and features plenty of draw distance, numerous lighting effects and shadows, high resolution textures (particularly on the character models) as well as particle effects from fire and smoke. It's still not the same as a 64-player multiplayer match, which would of course be impossible to replicate, but it's a stressful and challenging benchmark to run nonetheless. It also has the benefit of being very reliable, giving us the same results through multiple reruns.
