There is a constant drum beat from this list and others that native is the only choice. This is not good.
If you are talking about Photoshop color rendering, horseshyte...
What is super critical and very important is that you produce a very accurate profile of the state of the display. If you do that, Photoshop will do a working space > display profile transform and you'll get an accurate display on screen regardless of the white point or gamma of the display. Forcing a white point setting and/or a gamma on to the display does ZERO positive benefits for Photoshop's display capability...you can have a D50 gamma 1.8 display side by side with a D65 and gamma 2.2 and Photoshop will accurately display the same image with the same appearance on both displays (assuming you have accurate display profiles for each).
What you may or may not gain by forcing a calibration is subjective based on the display, the card and the OS...but in this day and age of pretty standard and commoditized displays, you may do more harm to the display environment by forcing lut adjustments in an 8 bit display system.
On the other hand, spending the extra bucks to buy into a display system that exceeds the limitations of 8 bit display tech might seem over the top for some people. But if you care at all how your images appear on your display and the accuracy of the image appearance important to you, then I wouldn't be futzing around with a display that is limited to only 8 bit lut adjustments for calibration. You get what you pay for and if you buy cheapass displays, then don't expect high performance and accuracy.
