Epox 9npa+ w/ big video card

I'm buying a computer I will use for video editing and encoding. For video encoding CPU clock speed is most important, so I need an overclockable MB for the CPUs. I want to overclock 3200+ to 2.6 - 2.7 GHz and X2 4800 to 2.8-2.9 GHz.
I'm not going to play any games, so I don't need any 3D functionality, SLI and fancy video cards. But I need a videocard with HD Video support and good hardware MPEG encoder.

The boards with good benchmarks and overclocking capabilities I can buy on are two

Epox EP-9NPA+ Ultra
MSI K8N NEO4-FI

(ASUS A8N-E doesn't have FireWire and DFI Infinity requires too much tweaking, I can't afford more expensive desks)

I was going to buy Epox from the very start, but I've read about two issues with the desk
1. It's vcore is the highest among it's class mobos with the same FSB
2. Good (= Big) videocard blocks both one of it's IDE slots and one of the PCI slots.

Do you know if it's true?

What do you class a high definition capable video card ? A 6200TC ? A 6600LE ?

Use this chart to select a card:

X1600 is more like it. With PureVideo I'll have to change to 7800 eventually, because 6-series don't support new MPEG-4 compression format (H.264) on hardware level and I want to stay with the same card for some 2-3 years.

Anyway, does 7800 block the IDE slot?

Yes, my 7800 GTX card blocks one IDE connector on 9NPA+Ultra rev 1.1 ...thats what i hate about this board. They should have thought of that and put the IDE away from the long cards.
Otherwise its a nice board.

Your CPU will have more to do with H264 than a GTX will.

heh...then there's ATI...i wonder i THEY are going to charge for decoding software, as does nVidia. What a crock that is!

It seems there are so many HTPC people reading spec charts and fantasisins rather than actually doing.

Makes me wonder also the place of am overclocked noisy PC when video is to be watched / enjoyed.

I'm thinking of the other people that are making these things or saying that they are going to make them overcrocked And note the difference between overclocked and overcrocked!!! One is done by the knowledgeable.

Which MPEG standards do you want to encode to? The cards you've highlighted so far do hardware acceleration of decode. The manufacturers stay very quiet about hardware acceleration of encode, leaving me to believe that the cards cannot provide acceleration for encoding.

Edit: Actually, neither nVidia nor ATi mention encoding at all. Draw your own conclusion!

Conexant don't do an H.264 encoder as far as I'm aware. They do H.264 decoders however.

Doh! V true - need something with capabilities like http://mainstream.indigovision.com/o...4-encoder.html which starts to become an expensive proposition since it needs something like a strongARM to control it.

Not on the SLI versions.

Hmm... I do remember watching DVD's on a K6-2/500 with a lousy Creative pass-through card. Seems like any kind of jitteriness people would experience with compressed MPEG on a comparatively monstrous 1.6ghz whatever + DX7-era video card would be more due to OS real-time responsiveness. Sounds like a job for Linux.

Neither Windows nor Linux are good for hard RTOS usage.

True - anything with a kernel running soft is going to bring a bottleneck to anything that needs to happen hard.

Well, that only does standard definition images, so HDTV is out again!

Ocean Logic have an IP core that'll provide H.264 encoding up to 1080p at 30fps. That can be implemented as an FPGA or as additional logic on one of the many processor cores out there. ARM and MIPS come to mind!
