    Even with the new GPUs, I did exactly the same installation as you, but still the CF is not 100% smooth for me. I see a little, very little lag when putting many effects on the scene at the same time.
    But our benches were equal with both 280S and 4870s, both CF and SLI...

    It's not quite an equal hardware since my installation was on a partition located on my external hard disk using usb. That by itself can make a huge difference, either to worse or better. I don't use a swap partition either. My CPU is constantly overclocked at 3.41 GHz, if some algorithms inside compiz are CPU bound they may produce different result too. There are so many aspects...

    True, but my CPU is now @3.25GHz (more or less close to yours)
    and I also tried installing the system on different HDDs, partitions,....stop.
    Could this be because of a swap? Will it run smoother without the swap partition?

    No idea Aikimox, I have plenty of RAM and I never use all of it to require a swap. When you use an external usb disk, the kernel uses a different kernel module too. It's not the same with the internal hard disk. This could possibly make the difference.

    This is very interesting! I'll try with no swap first , as it seems very logical to me that there's no need for it with 4GB of RAM, but creating the swap partition might lead to unnecessary disk utilization and even produce the lags I see....
    How do you normally partition your drive for linux?
    I did a 40GB root and a different bigger for the home.

    I only use 15 GB for the whole installation. I don't need anything more since I share a NTFS partition with windows 7

    Why would you not do a swap partition? The swap partition is only used when you exceed space in your RAM. This can potentially happen when running multiple instances of virtual machines. Thats also why I have 8Gb in lappie so I can run multiple instances of VM's without paging.

    Yes, but I'm trying to find the culprit of the laggy Compiz ( Stamatisx doesn't have this issue with a similar system).
    And besides, I'm not using the VM anymore or any other RAM eating software, so don't really need the swap.
