It's a nice monitor, but really you're paying for the refresh rate and 3d capability. If you want to spend that much on a monitor I'd look at a Dell 24" for their excellent colours. I game a lot, but even so 90% of my time is spent on desktop work, where refresh rate doesn't count for much.
I would suggest going with something cheaper though. Coming from an old tv, you're going to get an upgrade regardless, and you can always upgrade to a multimonitor setup later with the monitor you really want, leaving this one for secondary tasks.
