Celeron 440 +ATI HD3450 for HD?

I have a old 945G 775 mobo kickin around and a HD3450 which recently got replaced by a alot more horsepower. Slap in a few gigs a DDR2 ram a uber cheap Cely 440 (Conroe based). Would this rig have enough chops to do Bluray playback and a majority of my 720P mkv files?

If the HD3450 supports H/W acceleration for HD decode it might.

There's still a fair amount of CPU required for the DRM stuff and a lot of data to move around so the older chipsets might not handle it.

I know Athlon 64 3200+ was no good for BD/HDDVD playback even with a 8500GT which supported full HA for VC1 and H264. It played some movies fine @ 100% CPU but the majority were jerky. I have another rig with A64 3800+x2 (same 2GHz) with 9600GT and it has yet to stutter.

Conversely, Athlon 64 4000+ x2 @ 2.4GHz was able to play almost everything @ almost 100% CPU though pretty smooth with onboard 690G which didn't do neither VC1/H264 HA.

There is something about dual core that is making it right.

It will do the MKVs but won't BD.

The 8500GT was kinda inferior to the ATI offering. It didn't offload as much as the ATI cards, and when it did you had to be using its PureVideo HD which only works in Vista. I think ill give it a shot, if not dual core Cely's are dirt cheap.

My main rig had a 8500GT before a 9600GT - which is a really really good quality card though it is not targetted for HTPC - There is absolutely no difference is CPU use. These cards work the same with the Purevideo driver/PowerDVD7 that came with my HD ROM player.

I don't have a standalone ATI3450 but I have onboard 780G codename Radeon3200 which is pretty broken when it comes to hardware acceleration for VC1. It is better than any other onboard graphics however.

Any MKVs will require 4.1 or lower profile to be accelerated in which case you're fine. If they are 720p you can change the profile from 5.1 to 4.1 to make it work. For 1080p they need to be 4.1 profile native.

For Blu-ray you should be fine assuming your celeron is anywhere close to my P4 single core 3Ghz. I have the 2600XT Radeon and my CPU barely gets used.

Google "IDC Changerv0.2.zip" to get the app to change MKV profiles.
