Setting the three-screen scene
Just yesterday Sapphire released what 'it believes to be' the world's fastest single-GPU graphics card. Going by the name of TOXIC and equipped with a 'Lethal Boost' button, we found it to be plenty quick. Our benchmarks had it, on average, to be a hair faster than a partner-overclocked GeForce GTX 680.
Sapphire went to town on the TOXIC by also equipping it with a 6GB framebuffer - yup, 6GB of super-fast GDDR5 memory on a graphics card; I can remember when 6GB hard drives were considered large! Anyhow, our standard suite of benchmarks takes in 1,920x1,080 and 2,560x1,600-resolution settings, as found on 22/23/24in and 30in monitors, respectively, so the next step in the TOXIC's evaluation is to see what effect, if any, the super-sized framebuffer has when gaming on three screens.
There's little point in providing the TOXIC's three-screen results in isolation, so we have re-benchmarked a Radeon HD 7970 GHz Edition and a Gigabyte GeForce GTX 680 OC on the same trio of BenQ monitors, to see which card really is the top dog.

We're to show benchmark results from running a single full-HD screen (1,920x1,080-resolution) and then on three identical screens software-joined together by either AMD's Eyefinity or NVIDIA's Surround technologies. Running in accordance with previous methodology employed when using three screens, we are going to examine the average framerate, per-second framerate and per-frame rendering times. All will become clear as you see the graphs, folks.
