MediaPortal Forum - View Single Post - Poor performance With 1080p x264/H.264 encoded content

I really appreciate the advice. On your advice I purchased a AMD Athlon 64 X2 5200+ Brisbane 2.7GHz 2 x 512KB L2 Cache Socket AM2 65W Dual-Core Processor

5200+ was the newest CPU my motherboard had listed as supporting; I hope it is sufficient. Given the choice I might have gone with a faster 6,000 series AMD CPU but I didn't want to risk it as it wasn't listed as supported.

I considered going with a 3xxx series ATI card as it does sound like they do some tremendous offloading for h264 content (though if it is encoded in a non-standard way you are out of luck again and are depending on the CPU for decoding) but I do like the GPU I have now. I'm hoping the CPU upgrade will resolve the issue but if it doesn't I'll look at the 3xxx ATI series.

Also as a side note I did try using Core AVC and while that did improve playback so that the video actually moves along without stuttering the audio and video were out of sync and the CPU was pegged at 100% the whole time during playback; doesn't look like that is a good solution for my current hardware either.

*Update*

On further examination of the MSI website my AM2 K9N Platinum motherboard DOES support newer CPU's according to this list:

MSI -- MICRO-STAR INT'L CO., LTD.

So I canceled my old order, updated my BIOS and ordered a AMD Athlon 64 X2 6400+ Windsor 3.2GHz 2 x 1MB L2 Cache Socket AM2 125W Dual-Core Processor instead. It should be much more powerful!

Anyhow I really appreciate the response!
