ATI Eyefinity: Now you can run six monitors in HD from a single graphics card
 

Now we should point out that multiple monitors are nothing new, but in gaming terms getting a stable gaming experience while using the setup has been problematic.

Eyefinity (and the surrounding tech) changes that, and in spectacular style.

On the three monitors, the gaming experience was, in all honesty, not significantly worse than the six monitor set-up – and less likely to be pie in the sky for Mr average income.

Your peripheral vision extends far wider than it does vertically – and with the focus on the middle monitor, the side monitors gloriously plied our eyes with extra information without detracting from the gameplay.

The game being featured on this rig was Left4Dead, and it was certainly an advantage to be able to sense further around ourselves. It literally expanded our horizons in terms of gameplay – and, as a nice little added bonus – it made it much nicer to spectate.
