pc with blu-ray...

What is the minimum a new PC should be to play Blu-ray smoothly?
Would an Intel quad core 2.4 4g ram do the trick.
Does it HAVE to have a separate PCI express video card? As opposed an intergraded one.
What is the minimum mem for a video card on board/off board...

Thanx in advance,
Ron

Are you looking to build one yourself? Or buy one? Todays ATI HD video cards do most of the BD decoding on-board and make the processor less important. The number of cores is less important than the program you use to decode the video. If the software is not threaded for multiple processor you could have 75 cores, it will still only use one.

ATI makes a northbridge/southbridge combo that is called the 790GX that has an HD3300 video card built in. Most of these motherboards have HDMI built in. But you can't get the 790GX with an intel processor. If you are dead set on intel, you will probably want to look at getting an ATI video card like an HD4650. They are not very expensive and can be passively cooled. Let them handle all of the BD decoding and you can deal with a cheaper less powerful processor.

I use a dual core 3.0 Ghz Intel (925 I think) with a nVIDA 7600 GS with 3.0 GB of RAM and it works fine with the LG combo HD DVD/Blu-ray drive. See: HP HTPC (http://www.highdefinitionblog.com/?page_id=374)

Yes and yes, LOL...
I plan on getting maybe getting a barebones setup.

I edit with Vegas Pro 8. So, I want something that will be good for editing HD with Vegas, and Also burning and testing the burned blu-rays...

Yes, I have the same LG Combo. It is in my P4 2.9. Burned a few tests on rewrites, worked pretty good, but just can't play back.
Trying to find out the minimum that will play back. Is your nVIDA 7600 onboard or is it PCI express?

Here's the thing, I know I'm going to probably get flamed for this, but Nvidia can't do HD playback as well as ATI. Nvidia is the gamers card, but it's not quite as good as ATI at HD playback.

Like I said before, the newer ATI's with the HD chip in them will play back HD (ACVHD) video flawlessly. I use Nero 9 (showtime to be exact) to watch my videos and have no stutter at all. I have an ASUS M3A78-T motherboard which has the 790GX chipset in it. I also have an ATI X1950XT. My current set up has 3 monitors. One 20" off the X1950XT and one 24" and a 15" on the on-board video. When I playback my AVCHD files on the monitor that is hooked up to the X1950XT I can't stand to watch them. Too much skipping, audio and video lose sync and it's a mess. If I play the same video on one of the other 2 monitors off the on-board video, it's perfect. And that's an HD3300. For about $70 you can get an HD4650 that is passively cooled that will even do a little bit of gaming.

My suggestion is to simply get an ATI card for your current computer. Now, that's not going to speed up the editing much, but the playback will be great.

But all I have is AGP, I don't have PCI Express

Ah. I glossed over the P4 part above. Sorry. Yeah, PCI express is a good idea if you can. Last PC I bought was an HP with built in Nvidia. I replaced that with the X1950XT which is PCI express.

But with the new generation of ATI's you don't really need to put a lot into the processor. You might look for a motherboard that will allow PCI express and add a new video card to it.

There should be an AGP card that will handle the playback. The P4 2.9 might be a bit weak.

PCI express.

Here you go. No HDMI outputs, they didn't come until the HD4000 series. But Like I said above, I essentially using an HD3300 on mine.

rbinck, remember, when you move the decoding off the processor and onto the GPU the CPU is not as important. A P4 2.9 may very well be fine so long as the GPU is doing the decoding.

I will let you all know...

Haven't decided yet. Getting opinions on both sides dual or quad. Some are saying go with a faster dual core rather than a slightly slower quad core. Others say go quad core for sure...

Anyone know for sure?

Depends more on the software than anything else. In order for the software to take advantage of multiple cores it has to be threaded that way. Some software is dual threaded some is multi-threaded. Multi-threaded is better because the software can scale the number of processors used. So if you have a dual core, it will use both. If you have a quad core, it will use all 4. A dual threaded software will only use 2 cores no matter how many you have.

More and more software is being multi-threaded. I believe that the latest versions of WinDVD are.

I use Sony Vegas Pro 8 for my video editing, and just found out that it will utilize 4 cores. So it sounds like quad core should be the way to go.
But still the questions are:
Which would be better a dual core 3.3 or a quad core 2.4? (leaning towards quad)
Intel or AMD? (leaning towards Intel)
What type of PCI express Video card, like a minimum of what 512 or 1 gig? (leaning towards 512gig)
I do plan on 4 gig ram.
Plan to use VegasPro8 and Blu-Ray playback...

Thanx Guys for the input!

I just bumped from a dual to a quad and saw a small difference in processing time. The thing is, you aren't going to see one give you times of 3 minutes and the other be 10 seconds. Think of it this way. A dual core operating at 3.3Ghz essentially does 6.6 gig clock cycles per second. A quad at 2.4Ghz will do 9.6 gig clock cycles per second. Assuming that the software even spreads the calcs across the cores. BUT, there are other bottle necks in you PC that minimize the differences. Memory, FSB, etc, etc. So odds are you may only see a 5-10% difference.

Next, the video. People get too hung up on the memory on video cards. That really only matters to gamers. ATI's line of HD4000 series video cards has hardware decoding of AVCHD and BD built in. That means during playback, the processing of the video is shifted off the CPU and onto the GPU. And because of that, the video is flawless. ATI even has a motherboard chipset (2 actually) that incorprate this technology and even have HDMI outputs built in. They are the 780G and the 790G. So in reality, you could get one of those and not even need a separate video card.

So about all I can tell you is what I use:

AMD Phenom 9850 Black edition (quad core, 2.5GHz)
Asus M3A78-T motherboard (Has the 790G chipset from ATI)
I use OCZ memory (8GB at 800MHZ)
Also have an ATI X19050XT video card on the PCIexpress
I have 3 monitors.
attached to the X1950XT, I have a 20" Viewsonic.
attached to the on-board (790G), I have a 24" widescreen Viewsonic and a 15" HP. (All LCD)
I use Pinnacle Studio 12 (ulitmate) and Nero 9.
Playback is always done on Nero 9 Showtime.

The thing is, when I playback my AVCHD files (which is comparable to BD), if I put the video on one of the 2 screen fed by the on-board video card, it is perfect. Flawless. But if I move the video over to the 20" off the X1950XT it's crap. Jumpy, loses sync and becomes garbage.

As for actual video processing, I went from a dual core 5200+ (2.6GHZ) to the 9850. I noticed a difference, but it wasn't earth shattering. But it was better.
