nah a 27" would be too much.
i love multitasking though, facebook on a screen, a game in the middle and some other random shit like uTorrent and YT.
no more Alt Tabs for me mate. but im going for one screen at a time, same with the 670. probably run 2 screens on a single card then get the 2nd card for sli when i get the 2rd monitor.
