    In regards to open-source support for the Radeon HD 5800 series, we would expect initial mode-setting support to appear within the xf86-video-ati driver within weeks and hopefully we will also see kernel mode-setting support shortly thereafter or around time of the Linux 2.6.33 kernel, We would expect it to be at least a couple of months before there is any open-source 3D acceleration support for these new graphics cards.
    Sound like if I buy one now, it'll be running Compiz in one year ?

    It would be nice for Solaris and the BSDs which haven't implemented a KMS-like system in their kernels yet.

    I recall hearing more than between r600 and r700 but less than between r500 and r600 but probably not a good idea to take that for granted.

    The driver the 5870 ships with is a 9.10 beta (8.66)
    So it's very likley that the 5870 works with the 9.10 beta driver for Ubuntu 9.10.

    Yeah, well. I'd assume fglrx will get the support at the same time as Windows Catalyst. As to when opensource drivers pick up the support, we can hope for the best.

    Find first a game that can already overload an HD4870 / 4890 AND that runs natively with linux !

    Dual-booters (and I guess also VM setup?) would probably like a good gaming card for windows, that also has at least basic support (video,2D, and some degree of 3D) in linux. That is why I care about the linux support, anyway..
