Optiplex 3010 MT, cpu upgrade

Hi everyone hope you are doing very well. Well I would like to upgrade my Dell Optiplex 3010 Mini Tower, Core i3 3220 3.3 GHz -- I want to know what other processor can this motherboard support, i5 and i7. I have been looking information other blogs and it seems I can only upgrade to any i5 3rd generation processor but not i7. I will appreciate your help thank you!
