Hey Guys! Im looking to buy these creative speakers for my Macbook. I have one of the first generations of the Macbook purchased in 2008. here are the speakers, I read some reviews that said there computers sound card needed to be upgraded in order for all 5 speakers to work. Will my macbook be able to handle all 5 of these? http://www.upgradenation.com/751840/creative-inspire-t6160-5.1ch-desktop.html The speakers are: Creative INSPIRE T6160 5.1CH DESKTOP SPEAKER SYSTEM Thanks!
