    Just what I needed!

    The system has exceeded all expectations! It's everything I need and nothing I don't. Only two minor issues.. 1. The monitor arrived damaged. DE swapped it out right away. 2. I ordered it with Bluetooth 4 on board but it wasn't installed. The store gave me a BT dongle off the shelf, but it was BT 2. It works, but I paid for BT 4. Thanks

    We ordered 2 of these Dell Optiplex 790 I5's. They came running great and they are fast. We should have got 2 more. We will be looking for next sale.

    Five stars indeed! This is the second GX 790 tower and the fourth machine that I have purchased from Discount. Great customer service. The only down side is that the OS comes packed with what I call vendor spyware. Those are all of those little trial versions of programs. I happened to have a DELL OEM version of Win7-64 and re-installed everything. Drivers are all available from Dell so no issues. Tricked it out with a better video card, USB3 add-on card and 16gb RAM. For the price it's a true deal!

    Very Happy with my Dell Optiplex 790 tower computer Windows 7. It is fast and easy to understand for a not that informed computer user. Thanks will be buying from Discount Electronics again
