Was installed Photoshop Elements9, Photomatix Pro 4, PhotoZoom Classic4 and Nikon Capture NX2 and ViexNX2 (both were explicitly as 32-bit version shown).
All programs run flawlessly, a Geschindigkeitsvorteil is palpable !! That's what I wanted !! I could be totally at peace.
A minor drawback, there were but that language is English. Even if I could adjust keyboard and time and currency in German language is English. One can get used to it but reluctantly. Maybe that was why the package was so cheap ... That's why I've got a point deducted.
Windows XP I will erase soon because I see no sense in it.
