Is this computer powerful enough for 1080 playback? (1 Viewer)

Hi all,

I'm getting a computer tommorow with a P4 3.0Ghz CPU and onboard video. The motherboard will accept PCI-E graphics cards, so I was wondering if it would be absolutely necessary to upgrade the GPU? Also, it will only accept half sized PCI cards. I was thinking of getting an ATI 4350 as it has HDMI. So yeah, are the specs listed powerful enough for 1080p playback?

    probably won't, but no harm in trying it.

    I have an intel dg45ID which works well, and has a built in GPU (4500), but it is specifically designed for h264 1020.

    Unless its a really good on-board GPU its not likely it will be up to the task coupled with a 3ghz P4

    If you do manage to get 1080p running on the machine (either on-board or with the addition of a discrete card) could you post the results here? -- people are always asking the question about minimim hardware req's for HD and it would be an interesting point of reference for people researching this (including myself) to see how you get on with it.

    I have restored my 1080i playback with a N9500GT video card. I had been running 25% CPU using my on-board 7050PV to watch 1080i but now I think is a bit less (16%) but haven't really observed it all that much. I did notice that a (Shooter) 1920x900 .mkv I can use the MPV .264 Video Decoder and offload the GPU (hardware acceleration) such that what used to be 70% cpu is now about 8%. Clearly having a strong GPU is key for a quality HTPC!

    xclocked: Your CPU would proabably struggle for 1080p decoding of videos using software acceleration, even with coreavc codec. Therefore you would need hardware decoding using a suitable graphics card or onboard graphics chip. Since the CPU is slightly old I would guess that the onboard graphics would be old too and not up to the task. If you get a new graphics card that does dxva then you would be fine for playing *most* 1080p movies. If you had a 1080p movie that was badly encoded and not compatible with hardware acceleration, then you would still get choppy playback.

    You could try 1080p with your cpu and coreavc codec, and see if you are happy or not with the quality.
