Wonderin if anyone has one of these?!?

I am planning on running on 23' for my main maxed out and another 22' with my four alts. When I push this setup I tend to have to run my alts on super low settings. Will this gfx card help out or should I go cheap and buy a matching 9800GTX for the second monitor?

FYI ~ Leaning toward dual graphics cards pushing two monitors.
