Ati eyefinity, il multi monitor non è piu' un problema.

Ati eyefinity è la nuova tecnologia Amd che permetterà di collegare fino a 3 monitor per la 5870 normale, fino a 6 per la versione six. Con questa nuova tecnologia sarà tranquillamente possibile gestire piu' monitor in 3d contemporaneamente, riuscendo inoltre a inviare sui diversi pannelli flussi del tutto differenti.
