Do Not Buy Nvidia Cards For Linux!!!!
I have been knocking Ubuntu and big distro's for extremely slow screen response and lag compared to windows. I know many, many people on forums are thinking the same thing - Linux has bad response compared to Win.
Then I bought a new laptop with Intel video, and despite being half the spec of my main Linux workstation PC, the laptops Gnome session runs as fast as Windows. Then I purchased another PC with Ati video card, and that too was as fast as Windows e.g. instant response from moving windows and scrolling Nautilus/Browsers etc. Only the first PC, with NVidia video card, has terrible response (although the infamous Placement=2 line gets me a touch closer to the speed I'd expect).
Then I stumbled upon the Nvnews forums and learnt that my 8600GT video card is effectively a three legged horse in Linux due some mysterious problem with the drivers/x-rendering. Anything beyond 6 series Nvidia cards have worse Linux 2d performance than the cheapest Intel/ATI card. Even top of the range 8800GT etc...
I just kitted out a new business with 8 new machines and made sure none of the machines have NVidia video technology.
I am posting this message on Ubuntu forums to warn others. NVidia absolutely must get this sorted but from what I can gather havent even made an official comment to acknowledge the problem.
This is true at least in my case. So now I know why my Ubuntu is slow and laggy
I have to buy a new laptop or change the graphics card.
I tend to blame ubuntu for graphical issues rather then Nvidia, I have never had a machine that Ubuntu has not had graphical issues with but other distros work perfectly with, including an intel chipset as well (Mandrake as it was back then however worked fine). For my current machine which has two GeForce 8800 GTS (640MB RAM), an install of Ubuntu showed several graphical problems (split screen, blacked out parts of the screen, mirrored display), CentOS however seemily works perfectly with my graphics cards, even tho it's a server distro, not a desktop one like Ubuntu.

Let me ask the same question that was asked in your first thread: did you set up the proprietary driver at all? I have been using nvidia for a few years now and I have never experienced anything like what you describe providing I do not use the open source driver if they are newer cards.
FWIW, I also have ATI cards on a two other computers and I have to say that I see absolutely zero difference...
I have always had great luck with using the Nvidia driver from their site. But each to their own. But I can agree that some distro's have preformed better than others on the same laptop or desktop. But all it takes is a little tweaking and the one performing bad will be at the same level as the one working correctly.
