Here is a good list from newegg for good monitors in your price range. HERE
However, my personal favorite is the Hyundai L90D+
. I personally own this monitor and I dont have a single complaint about it. Tilt/rotate/raise-lower features are great, dvi and vga inputs, built in speakers(I would recommend getting another set of speakers though if you dont already have some). It works perfectly for all of my high-end gaming needs, no lag at all. However it doesn't look like you do much gaming with your graphics card. Viewing angles are very good also, so watching movies on it is very good. If you are looking into using it mainly for movie watching I might recommend getting a wide screen monitor. However that could cause the price to jump some but probably not overly that much. The hyundai though is a great monitor! Hope that helps!
