Hmm interesting.

I recently upgraded my 9600GSO to a 260GTX I noticed that on my 2nd LCD, even in windows, the picture is a little bit 'fuzzed' now at the same resolution and refresh rate...it's something to do with the new card.

Performance upgrade was huge, I get 40-70 FPS on my main wow client now as opposed to 18-28 I had before (slaves are capped at 15fps), but I'm a bit upset by the fact that everything is a *teency* bit fuzzy on the 2nd LCD now...
