Same here. My fast desktop with Core i7 920, Nvidia GX 240, has a slower KDE UI than my 6-year-old laptop that has AMD Athlon 3200+ and ATI Radeon Mobility 9700. Simply opening a konsole window on my desktop with compositing enabled can take 2-3 seconds, when it is instant on the laptop. People have been complaining about it for years, KDE and nvidia-drivers don't always get along with each other. The usual answer is that it works with Intel and ATI cards, and Nvidia's drivers are closed-source, so nobody can guess what the problem is and all we can do is hope Nvidia in their ivory tower can one day bless us with an update that makes things better. And then of course there are people who have Nvidia cards and everything works great and they don't know what the complainers are talking about. :) In my personal experience, on my Nvidia machine KDE 4.2 was the fastest, and it has gotten slower with each subsequent KDE release (with 4.5 being the worst one yet - so bad that I've disabled compositing entirely). Or maybe it has gotten slower with each nvidia-drivers release over the same period of time, I can't say. Maybe it is all a coincidence. However, on my old laptop with xorg radeon drivers, it has been getting faster with each KDE release, with KDE 4.5 is the fastest one yet. Both machines run latest everything on ~amd64. The only significant configuration difference between the two is nvidia-drivers vs radeon.
