"Maybe old, but they can upgrade it with new drivers do to it being a dsp chip."
that DSP wasn't even as powerful as the Vortex 2 chip, BECAUSE it was a DSP. why? becuase the Vortex 2 chip is hardwired for what it does. it did EAX in hardware, just like the Live could (ie no CPU hit). I know, I have EAX enabled in some games, and I see absolutely no hit.
BTW, you can only upgrade a DSP so far. performance becomes the limit on the DSP quickly when you start talking about Dolby Digital decoding onboard, while playing a 3D game and also doing MP3 in hardware (with a GOOD audio codec!).
