Need Better Computer for Learning Graphic Design

I am Ruso from Georgia. I live in Tbilisi with my 2 sisters and my parents. Despite our poverty I strive to become successful designer, which is my dream.   I learned drawing by myself and here you can check my drawings:http://shizuneru.deviantart.com/gallery/ I need better computer to study further and use more powerful programs for creating animations.   Drawing is not very profitable job in my country, so that's why I am learning design in computer. Please, help me to use my skills and knowledge for the benefit my family and community. I will never forget your help if you help me with this,
