Hi, dear all:

Just a fast question, does anyone have a real world experience on editing HD videos? We try to switching from SD video to HD video workflows, and are planning for purchase the latest 8-core 2.8GHz Mac Pro for such tasks, how many GB of RAMs will you recommend to install on the Mac Pro?

Does the rule of more is merrier still hold true for this case?

Just try to balance between costs and performance for my company, you know (under current economic situations... )

Thanks in advance!!

    Sounds like you might or are looking at the 2008.
    Having 8 DIMMs (8GB RAM) helps get the best bandwidth.
    So it isn't always how much as long as you have enough.

    cpu matters and there you can go with 8-core 3.2GHz for "only" $4000, not bad, or $2400 for base 2.8GHz 2.8GHz.

    Then add the storage raid controllers and drives you'll be wanting.

    I have a Mac Pro 2 x 2.8 Ghz Quad-Core Intel Xeon, *+10G 800 Mhz+* DDR2 F8-DIMM and 7 Tb of space disk (4 x 1.5T internal + 1 Tb external).

    Every morning I have my preferred applications started: Mail, Safari, iTune, Aperture and Final Cut Express. I just did a test for you. I started Mail, Safari, Aperture, Final Cut Express, Starry Night Pro Plus (OpenGL Astronomy Software), Terminal, Quicktime, TextEdit and NeoOffice.

    With all these apps running, I still have 6.48G of Free RAM out from the 10G installed!

    It's when I start hungry applications like VMWare Fusion running Windows XP, or Quicktime with a lot of movie opened that I could see the memory level going low!

    Your bottle neck in video editing will probably be the video card, after the disk speed. Be sure to use 7200 RPM disk and eSATA for your video plans if possible. Firewire 800 will works fine on external drive but it could giggle. I had an ATI Radeon HD 2600 that I recently upgraded to an ATI Radeon HD 4870. the drivers aren't ready yet from Apple. We are all waiting for the next OS X release 10.5.7 for the drivers! For now, I am running on Beta drivers.

    It's hard to say by now if I have better performance into Final Cut Express because the movie I was working on was an animation movie using plans exported from Starry Night Pro Plus via Quicktime and "animation" codec without any compression. As soon as I make a modification, I still have to render the output for smooth playing.

    For your memory, don't pay Apple price, they are totally out of price. Try OWC instead (Just google it)...

    P.S.: Apple Store say that you have 4 eSATA bay that can have each 1Tb disk for a total of 4 Tb of disk space. Actually, I found a link talking about two extra eSATA connectors not documented by Apple. And it is true!

    I first got my Mac Pro with one 500 Mb hard drive installed. Then I bought two others 500 Mb drives from Apple store.

    Finally I discovered OWC store. I replaced my three 500 Mb Seagate drives with 4 x 1.5 Tb Seagate and it is working extremely well. In fact, one drive was dead after only one week and OWC shipped me a new drive with no cost! I recently bought from them the two eSATA extention kit for 25.00 $ and I run my 1 Tb external "MyBook Studio" via one eSATA external connector for my Time Machine backup drive and everything is working very well.

    Now, that said, I payed less for my 4 x 1.5 Tb drives than I had to pay for my two 500 Mb from Apple Store. I really don't understand how Apple are still keeping their price that hight!!

    Similar low price for my memory...
