I only can tell you that if you only want to host a server it IS better... the difference between a dedicated and a non dedicated is that you do not play on the computer with the dedicated.. that menas it can run the whole day.. people can join and disconnect and it's running all the time... and therefore has better performance...
anyway there are tutroials at http://www.unrealadmin.org and there is a "Server Administration" subforum... maybe post there for more specific advise...
