Need an i7 3770 CPU For My Youtube Channel

Hi there, I run an very small 32 subscriber youtube channel named Cipher Gaming South Africa and i currently use an i3 3240 CPU. If i can get an i7 3770 CPU then it will allow me to vastly improve my content, cover a wide variety(including newer games), minimize to even eliminate low frame rate issues, have better graphics & have an smoother experience for the viewer however due to being unable to find work the past 4 years, I'm asking for help, I'm trying very hard to create an income for my family and i but i'm not able to afford upgrades, in fact my PSU & Graphics card is giving me issues, they will need to be replaced as well but that's going to cost me $450 minimum and naturally that's money i do not have, I can get an i7 3770 CPU on Amazon for $100, Any help will be greatly appreciated
