    If you dont want do decode 1080p50/60 (possible with some hd cams, but usually 1080i is default there, ) then a simple geforce 210 would be enough as well, but the price difference is getting smaller. The gt 520 is no gaming card, those are gts 550/gtx 560 and up. I dont get the point with compiz, i only use kde but never saw those performance issues even with a simple geforce 405 (rebranded 210). Maybe u does somethig wrong The mplayer example must be a joke as the test file is encoded at a very low bitrate. This can not be compared to max 40 mbit full hd which are within bd spec (8 mbit are reserved for audio). The best player currently is xbmc for those formats. vlc could use vdpau via a wrapper but this works very inefficiently. mplayer is ok with vc vdpau overrides, but with simple iso image support xbmc is my favorite.

    Using the correct driver would be part of setting the hardware up correctly to me.

    It actually WASN'T a driver problem. The driver I used did in fact have support for the card. Hell if it wasn't I would have been stuck at VESA modes and I doubt the HDMI audio would have been there. BTW the card was used AGAIN this time with Ubuntu 11.10. Still the same problem.

    I actually ended up finding what was causing this, largely because even after using the card with the latest version of Ubuntu I still had problems. Remember the benchmarks not too long ago regarding compiz? Well compiz was killing the performance (again the 430 doesn't have this problem) so even though I thought compiz was off, it wasn't. I had to completely remove it actually I uninstalled the ubuntu-desktop package entirely and went with Xfce. Bingo bango there was enough performance for decent video playback. Not unbelievable, but much better than it was. It was in fact usable. It's safe to say that it could be used for HD playback. However, it's just enough ...no more. There are still some very very rare cases where there's a dropped frame but it's largely not noticeable.

    I would still keep my recommendation that since the price of the 520 is pretty damn close to a 430 I would take the 430 over it any day of the week. The 430 is an older card, but it is in fact more powerful.

    There is something wrong with your picture

But when I installed it, it could barely play back HD content, while the 430 had no trouble with it at all. Maybe it's different in Windows, however for Linux use only the most boring HD content could be run without issue.
    I can play HD with a 32MB MX400 which is the lowest of the $9.95 low, but you're saying a GT 520 can't? I'd sooner believe you don't know what you're doing setting the hardware up. I'm sorry! Granted rebuilding mplayer locally helped a lot, but still. What I mean to say is it takes a bit more than just dropping these things into machines in order to get out of them what they can do.

    It is Nvidia or nothing on Linux for me

    No, just unreasonable and near-sighted. I even said if one wants hardware video acceleration right now, nvidia is preferable. I also said that g3dvl is in its infancy and that AMD has hired more devs for open-source development. So, don't think that things will never change, but don't expect tough work to happen instantly either.

    ATI is so poor that I consider it a rip off even when I get their trash for free! Time is money and it takes me time to pull that ATI junk out of systems. Nvidia is an honorable company and as such deserves respect from Linux users. AMD does have a lot of tough work ahead of them if they wish to earn anything from me. I'm shopping for a video card now and you can lay your last nickel on the fact that it'll say Nvidia on it.

    About card brands, those manufacturers often program their own clock speeds into the card's BIOS. If the card isn't clocked fast enough for HD video you of course run into problems. However, manufacturers usually overclock, lowering the max. clock speed is not that common.
    The 9600 gso wasn't a high end card, either. The core clock was lower, and the 128-bit memory didn't help. I'm seeing similar performance - same settings and resolution - running darkplaces-quake1 on the gt 520. Not an intensive benchmark, but the point is it wasn't high-end. Also, the vdpau benchmarks were much lower on the 9600 gso.

    Might have been a problem with your system because I was able to watch any HD size video all the way back to a 9600 gso on linux. I always found the opposite true, on windows, less support for higher frame references for avc videos using mpc-hc, the only player I know of that can use unencumbered dxva for video files. Or maybe it depends on the card brand, although I doubt it.

    I see no problem with 290.10, with 295.09 i had some issues with hdmi sound. Maybe U is crap
