I haven't read reviews of this screen or seen it in person unfortunately. However, I checked the specs and also looked at the user feedback as found on the newegg page:
Pros: I'm using three of these monitors in an Eyefinity setup at 6040x1080. It is just amazing. The monitors are excellent. Great picture, great for gaming. I was worried about low priced monitors, but these have exceeded my expectations.
Cons: No display port, but can't expect that in this price range yet.
Other Thoughts: Received rebates without any issues.
Its a TN panel, which means that you would have issues with the screens if you run them in portrait due to the viewing angles, but they have a decent landscape angle. Even though there were a good feedback in running this in Eyefinity, I would still check reviews about the anti-reflective abilities of this and other screens you consider. Some TN's are very glossy and can reflect all light around you, which is especially annoying when you have 3 of them.
Here's WSGF's tests of the 5850 with 3 1920x1080 in Eyefinity:

And here's the adapter I would recommend you get (which you need for the third screen/DP screen):
