OK... So how about  IntelCore 2 Duo E8600 3.33 GHz Dual-Core Processor?

The Wolfdale Core 2 Duo E8600 3.33 GHz processor should work fine.

Prior to installing the processor, check that you have the latest BIOS version installed, with version A11 updated Intel Processor's microcode was added.

But as i see on the Intel website, my chips model is compatible with core 2 quad and core 2 duo, Pentium Dual-Core... 

and i think these processes are compatible with the chips model... but not sure about the motherboard if it's compatible or not:emotion-8::

Q8000 series Intel® Core™2 Quad 4M, 1333 FSB

Hello again...

I have received the processor and i want to update my BIOS, there is newer version than A11 which is A16 ... 

So it's OK to install A16 instead of A11...:emotion-42:

I have a Dell OptiPlex 760 with OM858N motherboard (Intel chipset Q45/Q43), and a Wolfdale Intel e7300 that apparently doesn't support 64 bit thru the BIOS (A16), so I'm looking to upgrade to an e8000 series Duo Core 2 processor and need some advice on which processor to go purchase and how to get this so the BIOS will allow virtualization so I can have 64 bit capabilities.

Help appreciated!

Thanks - Rick

Intel® Virtualization Technology (VT-x)  is supported on Optiplex all the way back to the GX620 with Pentium D 960  2006.

VT-d is not guaranteed on ANY of the core series.  Not sure what you mean by 64 bit not supported because that too goes back to EMT64 as early as 2005.  None of these systems is a VMWARE ESX server with XEON processors.
