    Hey guys, anyone know where I can purchase an Intel Xeon W3680 CPU?
    I want to upgrade my current CPU, and can't find anywhere online\local that has this CPU in stock.
    Ebay is the only place, but they want $750 for used chips, where brand new online most sites list the price at $650 brand new, just no stock :(

    anyone know any stores that I can get the chip from, besides ebay?

    Keep hunting and be patient - search worldwide and you will find them cheaper, just make sure they have a 7 day DOA return option so you can test it thoroughly and the seller has excellent feedback.

    Last one I bought (used as usual) was a few months ago was from Germany for a client and all in with shipping was just over 500 bucks. Bought from Japan, China, Hong Kong and Taiwan before and so far fingers crossed I've yet to buy a duff one.

    Do not get too focused on the 3680 the 3670 is out there as well. It runs at 3.2ghz and last time I looked it was going for around $300-350, much better value for your money. If you see one for sale by xtrememicro I believe it is in Hong Kong or China on Ebay those are the people that sold me my 3680 I used to have. BTW where were all you people when I had it still for sale couple of weeks ago...

    I've had some good luck with "used lots" on ebay. You end up with about 50% junk in most lots. But then I've paid less for a lot with several good chips than I would for one good chip.
    However, almost no one sells a tested lot or gives any kind of warranty on the contents other than they will match the picture.

    Your welcome I see many people get focused on that 3.33 chip to their fiscal disadvantage so I have started mentioning that chip and really your not going to notice that 3% or so slower chip in there most times anyways.

    Search ebay for W3690 Xeon, they are $570 and free shipping. Best single CPU you can buy the Mac Pro.

    I called a bunch of stores today, no-one can get any new W3680's. So it's looking new a used one from ebay is my only choice. Worst part is the used ones are $100 more than the new ones would've been.

    Going to have problems finding new because Intel has discontinued those to the retail market months ago.

    ----------

    Quite likely flushed because stopped being a product in 2013. So closed out at the end of 2013 and dumped what ever inventory they had back to Intel or to secondary markets.

    I ended up buying a used W3680 from eBay. Should be here in 3-4 days. Any tips for install? I know I need a long 3mm Allen Key, and I have some ARCTIC MX-4 thermal paste lying around, any thing I need to look out for?

    2009 4,1 ? Don't forget to flash your EFI first.

    Forget the Allen key T15 screw driver is the tool for the job, you want it 4" long thin (1/8") shaft cost under $5 here when I bought mine. If your upgrading the ram to 1333mhz then once the new processor is installed you need to reset the pram to get it to see/use 1333mhz speed.

    How much you get it for?

    Be sure to run the firmware update utility before doing anything to make sure it's on 5,1 before installing new CPU. I used a sacrificial Alan key since I couldn't find the right size and just filed it down to for lol.

    You also don't need to get carried away with the arctic silver. When loosening/tightening the screws be sure to do each screw a turn or 2 then go to the next so you get an even pressure.

    I already updated the firmware on my 4,1 to 5,1 and I'm running 3 sticks of 1333mhz RAM, so I should just have to PRAM reset after the CPU is installed to take advantage of the faster ram.

    I'm gonna check the local hardware stores for an Allen Key T-15, I don't have one at home, but this and thermal paste should be all that is required? Actually I might buy a can of compressed air to clean out the heatsink\fan, since there is probably a ton of dust lol

    and lastly it was a bit pricey since you cannot buy them new online anywhere, I checked for hours trying to find them new, so I had no choice but to get a used one on ebay for $700

    Any reason you didn't want to go with the W3670 for half the price?

    Yes that is all that is required for you to see it/have it used, while your at the store get a bottle of isopropyl alcohol to clean the heat sink off of the old thermal paste.

    There are some differences with W3670 and W3680/90.
    http://ark.intel.com/products/47918/Intel-Xeon-Processor-W3670-12M-Cache-3_20-GHz-4_80-GTs-Intel-QPI
    http://ark.intel.com/products/47917/Intel-Xeon-Processor-W3680-12M-Cache-3_33-GHz-6_40-GTs-Intel-QPI
    Look at QPI and RAM:
    Up to 1066MHz and 4.8GT/s on W3670
    Up to 1333MHz and 6.4GT/s on W3680/90

    Probably not very noticeable, but some might be stressed knowing there's something *slightly* better out there! You know how it is... gotta be on top! :p

    I picked up a W3690 3.46Ghz for $650 on eBay. (From ebay seller "Central Valley computing parts inc").

    Great seller to deal with, seems to have all sorts of CPUs in different denominations every now and then. Might want to keep your eyes on him.

    Someone has one for $565 right now.

    I remember reading success stories of people upgrading Mac Pro 5,1's with i7 980x CPUs. That might be a more viable option if stock is drying up for the Xeons.

    And then you can run non ECC memory too. I'd go for a 990x.
