plan to get an edifier 5.1 will this be great affordable and complete for my needs..?
hi.affordability wise..yes. the question is from what you've mentioned "complete for your needs", i.e. movies, games, sounds or even karaoke. i doubt it. everything has it's limitations. it may satisfy your taste when it comes to watching your favorite movies, but has it's lows when you played your favorite music.
take it slowly. one at a time.
