Did you install every font you got?!!? For what reason? "Yay, now I have to scroll through 2000 fonts in that tiny box in PS before finding the one I want"
Plus I've got the impression that a lot of fonts in the Font-directory slows down both Windows and PS startup. Everytime.
No seriously, don't you have a Font Manager? I recommend it! Have a Font collection somewhere else on your harddrive, and only install the fonts you need. You can customize the sample text and size, just to see how that specific line of words look like.
I have been using The Font Thing for quite a while. It's a really old (1999!) but works perfect with a simple interface. Only con is that I don't think it supports OpenType. But that collection you bought was TTF only so it's no biggie...
It's FREEWARE (no ads or spyware), I truly recommend this.
I haven't really cared that much for OpenType fonts, but Opcion Font Viewer seem to do the trick. Not as good interface as The Font Thing (you can't install fonts to Windows/Fonts from inside the app, you have to do it manually), but it works, and is OpenSource.
