I have an Optiplex 760 Mini Tower with an e7400 CPU. I originally thought this supported VT-x extensions but it appears from checking at http://ark.intel.com/VTList.aspx#26547 and via http://www.howtogeek.com/howto/linux/linux-tip-how-to-tell-if-your-processor-supports-vt/  that my specific revision doesn't. I therefore want to know if its possible to easily upgrade to a CPU which supports VT-x ?

Either another Core Duo such as an e8400 or a quad such as a Quad Q8200. Both are listed in the OPTIPLEX 760 Technical Guidebook. I particularly wasn't sure about the Q8200 as that uses a 1333FSB so wondered if it required a different motherboard.

Can anyone offer advice?

Thanks
