Another point to really consider alot is if you plan to race it alot. To me thats a big difference because if you dont plan to race much then it has alot to do in how much money you spend. And you know if your not going to race it you can spend less money and not buy a top dollar race converter. The converter was very important in my build as I knew I was not going to race as much as I really wanted to but I wanted top perforrmance as I wanted it to work real good when I did race it and I knew I was going to spend the extra to get a top converter.
