OPTIPLEX_760MT
Hello, I have an Optiplex 760 with 0G214D motherboard and an E8400 Core2Duo. I want to upgrade to Core2Quad processor. I would like to know if I can and which one? Also, my PSU is a Corsair 550W. Thanks!!

Have a look at this website: http://www.cpu-upgrade.com/CPUs/Intel/Core_2_Duo/E8400.html1344

The max CPU your MB can take is the Core2Quad Q9650. It'll give you 64% better performance over the E8400 according to game-debate.
Remember to update BIOS first if not already.
I bought my Q9650 for $41 off of eBay and it came in brand new condition. A couple of others may pop up when searching: Modded Xeon's - no And the QX9650 - no.
If you haven't done this already, you'll have the most notable difference in speed if you max the RAM and use an SSD.
So the 760 has been around a while and this question answered at least a few times already; answered by me included. So I added some info to go with this answer I didn't see in a couple of other threads.

Having the computer open is a good time to check or replace tthe CMOS battery. Low batteries can cause bizarre issues. I'd test or replace it first, run machine, power off & unplug, then replace CPU. Doing things separately, if any issues develop, you know where they're coming from.
Also, see the end of this thread, the last few posts.

Thanks for the answers , but in some threads I saw say that my motherboard doesn't support core2quad and other threads say that it will. I have the Bios version A16 (think is the latest) but I didn't check CMOS battery yet. I already have an a ssd. Also I m thinking about cheaper like a Q8300 or Q6600 . Is it still supported?

The Q8300 is on the list of processors in the tech guide that I gave a link to. It will only give you 27% better performance over the E8400 according to game-debate. Only 24% better performance for the Q6600. Neither would be worth the change.
If you're budget strapped, I'd wait to be able to afford the Q9650 off of eBay. Like I mentioned - it's only around $41. Be sure to get at least a 30-day return policy.
You have a nice PSU, right? So you'll might as well get the CPU right too.

Yes, my PSU is hx 520w Corsair. What about Xeon E5450 or better a x3380 which is LGA 775 think have the similar power with Q9650, but will Dell motherboards get the Xeons support?

I almost forgot to mention the socket type for the E5450 you were looking at is LGA771, not LGA775.
A couple of posts above, I meant to say "...PCI-e x16 slot..."

Please remember the Q9650 is the max CPU your 760 can take, period.

No Xeon's in Optiplex's either. Precision's (servers) have Xeon's.
You mentioned some confusion in threads on whether the 760 can take a Core2Quad or not. Remember, though the tech guide is backdated at the time of manufacture, the Q9650 is on the list of CPU's it will take.
With that nice PSU of yours, you might consider a nice GPU unless you already have one. The MB max for the PCI-e 16 slot is 75 watt. Anything over that, the GPU will need it's own power hookup.
If you do decide to inquire about GPU's, you'll probably get the attention of one of our Rockstars or other experts that's more adept with GPU's than I am. What is your goal? To have a light-medium gaming machine or other tasks you want speed for?
If you want your PC maxed with the max speed it can be, is your RAM maxed also?
