I have Dell Precision T3610 With Intel Xeon CPU E5- 1650 V2 @3.50Hz, 3501 Mhz 6Core. I would like to upgrade to the most powerful processor I can fit inside my computer? I read some where that it is the  E5-2650 v2 (2.6 GHz, L3 20 MB, 8-core, Turbo 3.4 GHz). Is that true,. If not Can anyone tell me which one will that be? And if I did buy it. Is just replacing the new one with old one. Or I need to do some more work to make it work properly inside my computer? Thank you for your help?
