    GOOD Seller. Placed a double order of 2 different brands of 500GB hard drives with this seller. Both items were exactly as described and as depicted in the photos. Shipped together and arrived as expected on time. Items were well packaged and arrived in great working condition. Great value and I will continue check out the selection of items and hope to buy from this seller again. THANKS.

    A great upgrade for my Dell Optiplex 755 Minitower

    My Optiplex 755 originally had an Intel Celeron 430 1.8 GHZ and running Windows XP Professional 32-Bit, 2gb of ram, and slow as can be. I put this baby in my computer, maxed it out at 8gb of ram, and I installed Windows 7 Professional 64-Bit on it. This processor added a new life to my Optiplex. For under 20 dollars, you are getting one heck of a CPU.

    Good older processor

    It's an old CPU, but if you're upgrading an older machine with a dual-core, it's a decent upgrade. Clock speed not as fast as other quad-cores, but this one is much cheaper. It dropped right in to my old Acer and worked great.

    Easy to install but PC may have to have BIOs and drivers updated to work

    The CPU was easy to install. However, my PC had to have the BIOs and Windows drivers updated to work. Beware, my Lenovo M57p was built for Windows Vista and they don't make drivers for Windows Server 2016. There are no unknown devices under Vista but there are 3 unknown PCI devices under Windows Server 2016. Doesn't seem to affect the CPU though. My PC was at 50% CPU utilization with the original Core 2 Duo. It runs at 1 to 2% CPU utilization with the new CPU. Well worth the price!

    Q8400 speedster

    I originally bought these Q8400s to replace some E6300s in some Optiplex 745 and 755 SFF units. The 745s would not boot with the Q84OOs so I went back to the E6300 (ugh). However, the Optiplex 755 loved them and made those units a respectable desk top again. For a business office that is not heavy into graphic design and/or photo renditions, this is a big dollar saver. The price was low, the install time was 20 minutes or so and voila, a cooking little computer. I have used some ~3ghz dual-core that are pretty quick, but these Q8400s really get a grip when multitasking with web hosted apps, and local apps that depend on each other. And yes, I would recommend them to anyone who wants to ad new life to an otherwise slow machine. Don't forget to bump up the RAM to at least 4 gigs and ...

    Excellent choice for upgrade!

    Very easy to install. BGA instead of pins. Upgraded old Optiplex 330 computers from Core 2 Duo. Have used three, no glitches. Very pleased.
