    Thats because you are running windows drivers on linux with nvidia. Thats why they cannot open the source, cannot support Xorg properly and handle linux as second-class; but release fast and on the same graphical tests you can reliably mess linux always fall 20% behind winblows (unless its cpu intensive,ie kernel, then linux will win). Well, it is currently fastest 3D solution, but it lacks (and will always lack) any point where linux can actually use its main feature to go in lead.

    If you look at software performance(ie recoding, databases, processing etc) linux LEADS on opensource apps.

    In 3D it is slowed down by:
    a) a company that handles it as second-class system, never opens source and hence hardware+linux software solutions always fall behind winblows with performance to have no choice to go up or on-par(no one can improve it beside them, and they simply dont care).

    b) a company that does opensource, but .. ugh,.. slooow. It still carries its closed source driver, that is many times worse than (a), unless workstation tasks. A company that cannot deside? Well at least it does(together with some community effort) opensource and its 3D is usable.

    c) a company that does only opensource in linux. But its opensource drivers performance is messed to be 5-6 times slower than on closed source winblows. Wtf, no? And it has no hardware capable of something average 3D currently.

    Great 3D situation, no? The choice is yours. I went (b) and abadoned (a).

    If you do not want Opengl4 effects in linux(any apps using them?) and can live with opengl3.2 - go 4770. This is the only difference to my knowledge.

    the hd3000 and hd4000 do have a broken openCL gpu-cache! (its emulatet by software over the vram/ram)

    if you wana use openCL in the future only HD5000 brings you full speed!

    but only hd5850 and up do have full 64bit power!

    Where do you have this information from?
    HD3xxx isn't even supported with opencl.

    in openCL there are 2 gpu caches ...

    the hd3xxx can handle openCL but the 2 gpu caches are broken. so the speed is low low lowest low!

    the hd4xxx series do have 1 broken-cache so the speed is low to but better than hd3xxx

    yes because of this amd do not support openCL on hd3xxx cards!

    only hd5xxx cards have full compatible gpu caches for openCL!

    if you don't belive search in the forum about openCL there is a threat startet by me and bridgman write there to ;-)

    if you don't believe me call bridgman for this!

    "Each new generation has additional inter-thread hardware support and there's a certain level required for a full, fast OpenCL implementation. IIRC the global data share (GDS) was added to rv670 first, and local data share (LDS) was added to rv770 first, and both of them are required for OpenCL. "

    and this : ""To be (hopefully) precise, the LDS in RV770 isn't used in OCL, and will probably never be used there, as its access model is too restrictive to fit the specification.""

    We are not the ones suffering from grandiosity.
