Paul, I agree with all of your comments.
It is always a good idea to convert a file to the color space you'll be using. For example convert a *.psd file to sRGB if it's to be used on the Web. Images used in MS Office documents, as I understand it, work best if they are tagged sRGB. I do all my editing in Adobe RGB and allow Photo shop to manage colors when I print to my Epson R2400. This seems to work very nicely for me.
For my NEC monitor, I created a custom profile that SpectraView uses when I calibrate. It took a little experimentation to get the best profile for screen/print matching, but once done, life is easy.
With regard to video cards: Most of the higher end cards, like the Quadro Pro are designed for gaming, 3-D rendering or video editing where high frame rates, pixel shading, etc. are required. As you say, Paul, this kind of performance is not needed for photo work. A decent, passively cooled, 1 or 2 GB card will provide excellent screen redraws in Photo Shop or other image editing software. (Adobe has a list of CS5-CS6 compatible video cards that should be consulted before specifying a card)
"The spectraview hardware calibration is a thing of beauty and will spoil you. "
I can atest to this: I am definitely spoiled. It's so easy, you'll wonder if you missed something while the process is running.
