Whilst I'm impressed with the Hercules XP, it does have full 5.1, with a full six channels, so you don't need to run digital cable to the speakers. It doesn't seem, in comparison to my old MX300 to have a great a dynamic range. (Though Cambridge SoundWorks speakers may be more of the problem here than the card!) The EQ works, but needs a little more oomph. 5.1 needs to actually put into the program/music your running, because it involves special phasing and panning in the mixdown, so if you think your card is running 5.1 in a game which hasn't had it programmed into it, you actually only running 4.1. The XP also has things like a external game port, 4 extra USB's. It also keeps one of your internal bays free, unlike the platinum. Though on the other hand, if your tight for space, the xp sits on your desk as a breakout box and may prove to clutter your workspace...
