    So I'm looking to upgrade my Mac Pro to a better processor. Either of these processors would make a word of difference to my Mac Pro. Question is, do I go for the higher clock speed, or the hex-core processor? Here are the options:

    Nehalem, 4-core, 3.33GHz, 8MB of L3 Cache (W3580)

    OR

    Westmere, 6-core, 2.66GHz, 12MB of L3 Cache (X5650)

    Currently, I have:

    Nehalem, 4-core, 2.66GHz 8MB of L3 Cache (W3520)

    Basically, it comes down to the clock speed and cache. Right now, I this is my main machine and I hope to use it for video editing and rendering in the future with Final Cut X. Right now all I use is iMovie, and a few other apps such as Safari, iTunes, etc. Basic Mac stuff.

    I'm still transitioning from iMovie '09 to X, but I mainly use iMovie X now. Now, I know iMovie is multi-core aware, but will it use all 6 cores? And at that point, would the clock speed mean more then the amount of cores?

    6 core for video editing.

    Since you didn't mention about gaming. The overall multi core performance is more important for you.

    Also, it's better to upgrade for a more future proof CPU (better muitl core performance).

    Anyway, is there any reason for you not consider the W36xx series?

    Price. I'm looking on the used market, and the W3580 can be bought for ~$200 and the X5650 for ~$100. The W3670 is going for about $400 which is out of my budget right now.

    Thanks for your input! I think I'm going to go with the X5650!

    I see. I this case, definite go for the 32nm X5600 series, rather than stay at the 45nm W3500 series.

    It's cheaper, cooler, better multi core performance, lower power consumption, support more ram...

    Ebay is rampant with 5670s around $230.

    Can't beat that with a stick.

    I doubt you'd notice any difference between your current 2.66ghz and a 6 core version. If I were in your position I would be looking to increase clock speed (something you'll actually notice day to day) and possibly core count (x5670 as mentioned).

    For FCPX 10.1+ you should be looking into ATI graphics card updates. Running dual 5770s would be a good, cheap place to start.
    What GPU do you have now? Nvidia GT120?
