I'm looking for new speakers for my sys but i'm rather cash strapped and i'd like a 5.1 system, i've the choice between the creative Inspire 5.1 5100 or the Hercules XPS510. Any idea which one performs the best and what kind of connection they use?

the hercules is a bit more powerful and expensive but the control are on the subwoofer (which will be on the ground) and that is a big drawback
