So i have a completely stock computer with a motherboard that doesn't have a graphics card slot. I have a Intel Core I3-3220T and i would like to know if i can take the CPU out and put it in another motherboard and if so which motherboard and graphics card should i use for the best gaming use. My budget is $300. I have attached some photo's of the inside, also i have just noticed that there is no power supply. Please help me.
