Good all around
I bought this when I was using extremely slow single core CPU and my only sound device was external USB which was consuming 10-30% just to play mp3. This did the trick. It handles most of the audio task discretely so its great for older pc's. However, to get the BEST performance out of it I suggest going to the services menu and disabling the Creative audio services. They do nothing for you but do hog up resources.
I am no longer an old system but I have still moved this card to my new system. Modern cpu's of any kind have no problem handling audio processing of onboard codex so that's no longer an issue.
However, I do some recording and its nice to have ASIO support right out of the box. Less chirp sounds from on-board audio is nice (ie, every time i touch a volume slider or a piece of metal i would hear a small blip when using on-board audio...that no longer happens when using this card)
The sound quality is good. There are some 3d-enhancement features which I usually dont use but I think they are good for games. There is also a "Crystalizer" function which is..MAYBE ok for certain songs while using certain speakers but generally I leave it off as I find the sound is usally best with everything off.
There are 3 modes. Entertainment, Gaming, and Audio Creation.
Entertainment mode Seems to make effects most available. Probably best for watching movies.
Gaming mode Puts 3d CMSS in certain modes that are suited for games..I think it may also disable some channels to be more conducive for higher game performance.
Audio creation. Low latency ASIO and lowest processing. There is a tab in the config for selecting Bit-matched input and output (which disables certain eq and effects and in some OS will max the wave channel volume). This is how I generally leave mine and it sounds great.
Good card, but there is a reason they are cheap. If you are happy with on-board audio there is only a little bit to gain by getting this. If you want to do recording with an internal sound card this IS a good option though there is probably slightly better ones for more money.
All in all I am very happy with what it is. I paid $10
