    I saw the benchmarks here and they spoke by themselves.

    Saw the ones on Anandtech and I couldn't agree more:

    On the GT 520 and HD 6450:

    A discerning buyer building a HTPC system, having perused the various sections in this piece, would do well to avoid these two products.
    If you prefer only AMD cards, the 6570 is the perfect HTPC card.
    If you prefer only NVIDIA cards, the GT 430 is the perfect HTPC card for which you can obtain a passively cooled model.
    Thanks for the article!

    Does it matter that the codec support is optimized when the hardware itself is slower?

    As PureVideo HD performance is dependent on the GPU's core clock speed, the impact of PureVideo will vary depending on the speed rather than the 3D power of your graphics card.

    Also, since the 3D hardware isn't as beefy as the 430, it probably uses less power, which is a good thing when using passive cooling..
    Doesn't convince me yet. Intel GMA X3500 supports DirectX 10 yet you won't play Crysis with it. Does it matter that the codec support is optimized when the hardware itself is slower? I feel that any advantage in code is lost because of it.

    What you say is definitely incorrect. Btw. if you have got libva + vdpau-video wrapper installed then vainfo will show mpeg4simple which is used by divx. Most likely there is a test tool for vdpau directly too. xvba-video never exposed that or did you see it? if you recommend ati hardware because of video decoding hardware that only works within win then you are in the wrong forum i think...

    nv or older than hd6k have some hardware for mpeg2 that is used by xvid/divx codecs for the rendering , like " motion compensation " with ati rage pro was with dvd at the time of w98 - half-life .
    but hd6k is able to render the divx without any help from cpus
    nv made the hit with its 3d support while ati always do the best in 2d . now ati does some good 3d for a cheaper price than nv . by the way gpu market is 50-50 .
    i do not have a hd6k but that should be cool to know if ati-drivers are installing codec for divx with linux or windows

    Again, apples and oranges for the price and class of cards you're talking about..
    The competitor for the GT520 is the RadeonHD 6450 (also with a 64-bit bus). Considering that no AMD cards do full VDPAU in Linux (yet), there's no competition at all if that's what the card is intended for.
    ati was the first to have full hardware for mpeg2 , it was before geforce was born . with hd6k it has the DIVX in hardware .
    for the 2d and 3d , ati is largely better than nv .
    if "nouveau" drivers are not good enough to use full potential , that does not mean card is badly made .
