It's important to note that a system like the PC Specialist Vanquish XT-680 is no slouch - it's equipped with the world's fastest single-GPU graphics card and delivers great overall performance. But the 3XS Carbon SLI is something else entirely.
Showing excellent scaling across two cards and four GPUs, the dual-GTX 690 configuration scores a staggering 10,617 3DMarks. For comparison's sake, we scored 5,630 3DMarks when using a single GTX 690. Adding a second card results in an 89 per cent boost in performance.
There goes one of our standard benchmarks for high-end gaming PCs. Running Aliens vs. Predator at 1,920x1,080 with 2xAA, 16xAF and very high image quality is, as expected, too easy for the 3XS Carbon SLI.
This is a PC designed for bigger and better things, so we're doing our best to source a couple of extra monitors to re-run some of these tests at a more befitting 5,760x1,080 resolution. In the meantime, we cranked Aliens vs. Predator up to 2,560x1,600 with 4xAA, 16xAF and maximum image quality, and still returned a staggering 112 frames per second.
You get the idea. There's enough graphical horsepower on offer here to make most other 'high-end' PCs look like children's toys.
