Would a better Graphics card run HD mkv files better?

I can run 720p mkv files OK though with very slight jerkiness on my system (AMD64 3500+, 1gb RAM, Geforce 6800, Asrock 939DualSataII board) using Core AVC decoder Haali splitter and AC3 filter. But 1080p material is impossible - very jerky and juddery.

I am assuming my system should be fast enough and so a better graphics card is needed. Am I right? If so should I invest in the 8800? Would this solve the jerkiness? Or maybe I need to upgrade system?
 
Not sure as the 8800's are said not to have Purevideo2, as they came out before the newer midrange 8000 cards which do have purevideo2, I aint sure if the 8800 Ultra has or not as its a REV 3 core I get 22-25% CPU use in different HD type playbacks, on a 6000 and 7000 series I had 40-50% and without any Purevideo its was 75-100% (before 6000 series).

I do have the retail Purevideo Decoder but its outdated now.

Going by reviews on mid range 8000 cards in HD playback the drop from 40-50% to 20's% seems right for Purevideo2.

Hope some this helps.

i`d say its your cpu bottle necking the mkv playback as i only have a 256mb x1300 pro gfx card in my media centre system (slightly modded sony viao vgxl-100) but has a dual core 2.8ghz pentium d and i have no problems whatsoever with any form of mkv files or any other HDvideos.
i use ffdshow and haali splitter though but i always thought the core avc used less resources :confused:
 
Indeed, iirc the cpu does the calculating, so a new graphics shouldn't make much of a difference, the cpu would though.
 
Oh and BTW, for 1st time ever when installing K-Lite codec pack, I choose to let FFdshow do all my encoding, instead of Divx / Xvid etc.

The GPU does take the load of the CPU in Purevideo and ATI's equiv but not sure what codecs get full support so far, I was screwed on a 6800Ultra AGP with a broken PvP, it was only 6600's and 6200's that could do WMV-HD as they came out later and were revised, Nvidia did try make drivers support 6800's through software and MS gave hotfixes for WMP10 to help though, also I demanded my free license for the Nvidia Purevideo decoder after buying a £410 6800Ultra that was not doing what it was advertised to do.

Thanks for the info. Don't need AGP as the board has PCIe also. However to get a dual core CPU would involve new motherboard. So you are saying that 3500+ is just not fast enough to run these files?
 
Why cant your mobo take a dual core cpus, is it because its one them hybrids that can use AGP or PCI-E and has different chipset?, and your CPU would cope if you could get a GPU to offload some of the decoding.
 
You can tweak settings in it to use less or more CPU, I had to mess about with it and Descaler a while back to try upmix normal movies from PC to 1920x1080p for my TV but it still looked bad lol.

well according to asrock site your mobo supports dual cores cpus http://www.asrock.com/mb/overview.asp?Model=939Dual-SATA2&s=n :o
i cannot say how much improvement it would give though as i havent had an amd for a few years now :confused:

I can play 1080p with no problems (80% cpu usage with other stuff playing/downloading), on an Athlon 64 3000 @ 2.5ghz, same mobo as you. The 3500 runs at 2.2ghz stock so I wouldn't have thought it's the problem?

Are you talking to me? If so, I tested on the "Robotica" 1080p clip cause it was only 22mb, but I have also played "The Living Sea" in 1080p as well. Plays perfectly with other stuff going on as well. Is there a difference between the videos?

edit: Just clocked my CPU to 2.2ghz and it plays exactly the same. So I don't think the problem is your CPU Restorer.

Not sure if this helps, but just tried the 'Step into liquid' clip at 1080p on two different a64 machines. Both ran it perfectly, although nearly maxing out the slower pc.

pc1 a64@ 2.6ghz = wmp 70% cpu time, total was 85%
pc2 a64@ 2.0ghz = wmp 85% cpu time, total was 95%+
 
Put it this way... I watch 1080p MKV files with an onboard 6100 and X2 3800. No skips, no judders.

Graphics card is absolutely, truly not important at all for HD video. Processing power is.
