Hi all, I created a dell community account just to comment in this thread.
I like many others own an optiplex 790 desktop. I also like many others desired to upgrade the CPU.
Unfortunately I do not believe that the motherboard in these machines supports ANY CPU that utilizes intel hd3000 graphics.
For my own attempt, I purchased an intel core i7-2600k processor. Like others reported above I do not get any video output whatsoever despite having the latest bios (a17 in my case). Reinstalling the old i5-2400 causes the computer to resume normal operation.
I am quite disappointed in Dell regarding this issue. Only a couple of socket changes ago (lga775) you could put in any old core 2 duo or quad processor In most dell desktops assuming the chipset was new enough to support them. There is no reason for this artificial limitation to be imposed as the i7-2600k was released at the same time as the cpu's that shipped in this machine. The Q65 chipset also fully supports the intended CPU upgrade and it doesn't consume any more power than any other of the other quad core sandy bridge chips. There is no legitimate reason for this CPU not to work in these machines.
Not to mention the ridiculous pci-e slot 35w power limit but that's a rant I"ll save for another time.
Now that I've gotten that off of my chest I hope that dell will realize the significant inconvenience that they are causing some of their enthusiast customers and change their behavior accordingly.
