Looking at the stats on both of the monitors they look about roughly the same. Obviously, sometimes stats don't translate to how things look and feel in the real world, but when it comes to the important stats for a monitor like pixels, refresh time, contrast ratio, viewing angles, the two monitors have the same exact stats.
One nice stat on both the one that you mentioned and the one that I mentioned is the 2ms response time, which is pretty fast and great for gaming. Also, they both appear to have very thin bevels which looks great on an eyefinity setup. I can't say how the viewsonic appears in real life, but my wife's computer has the Asus and they look great. It should be noticed that the Asus might have an unnecessary feature in that it has speakers and I'm guessing that headphones or an actual speaker set would be used, but you don't need to use them (for my wife we don't even have the cables going to them)

The guy at Fry's said the viewsonics are better for gaming than the asus but i am not sure.
