The FP-955 is one sweet monitor. But if you are moving from a curved monitor screen, it takes some getting used to as the screen of the FP monitors is flat in vertical and horizontal.
Now that I have had my 950 (predecessor to the 955), I can't stand looking at fishbowl tubes anymore.
If you go with the 955, make sure you reset the color temperature to 6500K, from the default of 9200K. Makes for more natural colors, especially in the gray scale area.
Also make sure you video card and drivers can handle the plu-n-play features, so they can get the best (highest) refresh rates from the monitor.
