Hi guys, I currently have the Logitech Z Cinema and after hearing all the negative comments on Logitech's speakers, I was wondering if I can do with an upgrade on my computer speakers. I was thinking Klipsch Promedia or maybe the Rockit G2's, though I'm not really favoring the Rockit's due to their size and price.. I'm going to be using these for gaming as well as music. First off, will I notice the difference in quality with my current setup? Also, will the lack of a bass in the Rockit G2's be noticeable? I don't have a sound card in my PC currently, so will I need one? Other suggestions are welcomed as well!
