    Hello Guys,

    Does it make sense to upgrade X5650 to X5690?
    I know it's quite a lot of GHz but will I fill it? I am doing a lots of 3D rendering but more painful is Photoshop with big files so maybe its single thread low GHz frequency issue? I am using it with quadro 4000.

    All the best

    3D rendering usually able to utilise lots of cores. But as you said photoshop is not. If you are ok with the X5690's cost, it's actually worth to do it. If you rarely fully utilise all 12 cores, dual X5677 may be the very best option for you. They are much cheaper than the X5690.

    Thank you for your answer. I will just double check if there is any heating problem and I will go for it. Thanks!

    Both CPU option has been proved no heating issue. Even though the 5,1 never shipped with dual 130W CPUs. Since the cooling system is so good in the cMP and lots of headroom to take more heat. The worst case is just need to spin up the fan a bit (which also means more noise). Of course, the assumption is that the thermal paste is correctly apply, the heat sink itself is clean, the fans are working properly, and there is nothing block the Mac's circulation, etc. However, since the SMC may never programmed to handle dual 130W CPU. You may need to create your own fan profile. Or manually increase the RPM.

    I did his exact upgrade a while ago. It is worth it for sure if you plan to keep your 5,1 cMP for a while longer. It is the fastest single core and multicore setup you can get for this machine.

    If you utilize all 12 cores for rendering, is CPU speed is up there with the fastest nMP 12-core.

    The single core speed is also the fastest you can get on this machine, but is below most new Mac machines today.

    I went from two dual core 2.66 GHz to two quad core 3.0 GHz CPU's in my 2006 Mac Pro. It made a huge difference.

    While a different setup than yours, I would expect you'd definitely notice an improvement.

    I think you should get a pair X5690, they very cheap now, even you get pair only with 400-500$.

    Our tower is near end support and consider put fastest processor at least to add longer lifespan. Even i'm feel my dual core X5690 is "slow" and energy inefficient since I'm hands on with modern E5 xeon cpus.

    Thank you guys so much.

    So I need to ask myself.. 500$ and more speed to my mac pro or maybe windows :(. Thanks guys.
    And what about X5675 (3.06GHz)? I know that jump is small but it costs just 200$ and having same TDP as X5650 so no heating issues for sure.

    For $200 you can buy pair of X5680 (3.33Ghz). Performance nearly like X5690, no heating issues and have very reasonable price.

    I see the 5680s have a TDP of 130w while the 5675s can pull 95w.

    Have dual 5680s been stable in heavily-loaded, heavily-exerted systems?

    With fan control software, like macsfancontrol, and custom-made profile, system are stable and quiet on heavy load

    I second the use of MacsFanControl. I live in Sydney, Australia and the Mac Pro is my first desktop computer that did not have overheating issues in the summer months.

    I have a 2008 Mac Pro 3,1 which I upgraded from a single 2.8GHz CPU to dual 3.0GHz. I decode DVDs for my media library and now I have found that the speed limitation there is the bandwidth of the old PATA/IDE bus on the DVD drive.

    I won't buy a trash-can Mac Pro. Too expensive and lacks expandability. I would spend the money on another classic Mac Pro and give it all the upgrades that will go into it.

    I did the x5680 upgrade. I just didn't see the value of the small jump to x5690 for over double the cost. Machine is solid as a rock and with an SSD incredibly fast as well.
