Comtech, you have me confused again!
The whole point of PCI soundcards, as I perceive them, is that they can handle more of the audio processing because of the higher data transfer rates of this bus. I use an SB Live!, and there is many worlds of difference between this and my old ISA AWE32, good though it is.
I do a lot of audio work, and there is no way an SB 16 can cope with the full-duplex multi-channel loads I throw at it, so presumably there's something in the theory. Even the Live struggles with latency problems. If you have technical data that supports your assertion that PCI=ISA, I'd be extremely interested - maybe there's something I've been getting wrong all this time! :
Also, the Turtle Beach Montego is $50! how can you say that's not cheap? Especially for such a high-quality card - It's only $20 more than the Ensoniq, and $100 less than the SB Live!, which is its nearest competitor, in terms of quality.
Oren was looking for a high-quality low-profile card, and the Montego is probably the best in its class. I don't see a price-range stated, but I'd think $50 about right for a soundcard. I'd consider something like the Event Gina, or anything from DigiDesign to be expensive! ;-)
If all you want to do is games, then the Ensoniq is fine. If you're a little more serious and want high quality audio capabilities, the Montego is the only budget choice, IMO.
Many Regards
