Hello CD, I appriciate the help. Anyway do I realize that I dont need
the Video driver correction with a correct profile. But if the
calibration is not to my liking I can always resort to driver adjustment.

So If I get spyder 3 can I use XP with ndivia drivers and not adjust
them in anyway and profile both cards?  Or just use the windows
driver? But I tried useing the windows driver on a ati card and it was
unstable. Profiling 2 cards must be a new area for you guys. If it
matters I bought sli enabled cards but I never game so I will probably
 never use sli.
