It depends on what you do and the kind of codec that your future NF4 mobo will have. Old NF2 mobos came with a technology called SoundStorm, which delivered great quality audio (as far as I know, didn't own one). Better yet SoundStorm was the only onboard sound (as far as I know again) that offered native ASIO support, which is a must for electronic musicians. Unfortunately Nvidia eliminated SoundStorm for the NF3 chipset but there are rumors that SoundStorm will be back again for NF4.
- If you are an amateur electronic musician (like me), and programs like Reason, Traktor or Cubase are part of your everyday work with your computer, you should stick to the SBLive instead of onboard sound, that is unless NF4 come with SoundStorm. I've compared the onboard sound of my mobo (Chaintech VNF3-250 comes with a Cmedia sound codec) and the sound quality of the SBLive is far superior. Of course you wouldn't use the Creative Sound Drivers because they are crap, you'll have to use the KX Drivers(
www.kxproject.com), which are an open source version of the drivers that offers huge optimizations for musicians (including native ASIO Support). Take into account that the KX drivers are a bit complicated to configure and don't have support for EAX, and since they are not made for gamers, you'll have to usually adjust a couple of settings before playing games, and re-adjust them when you are back to music making. If you fall into this category and you have a few bucks more to spend, then you should go with a newer soundcard, something from M-audio(which will have all the bells and whistles for a musician) or even a Chaintech AV-710 (only $25 at Newegg), which offer great quality sound(better than the SBLive). Most people says that the AV-710 is almost like a M-Audio Revo, which cost 4 times more.
- If you are a gamer and don't care a bit about Electronic Music, Reason, Traktor or ASIO, then you'll have the choice of onboard or your SBLive(with creative drivers). With onboard you'll have native 5.1/7.1 support and usually some form of EAX support (important for some FPS games). If you stick to the SBLive with the creative drivers, you'll have better EAX support, a bit better sound quality, and less use of CPU cycles (although the Creative Drivers are a resources hog). If SoundStorm makes it back with NF4 mobos then with no question you'll stick with that.
Personally I'm using and old SBLive Value! card with my rig (KX Drivers). The onboard sound of my Chaintech mobo don't have the quality I need, and I wasn't able to configure the rear channel as an independent channel to use it as Headphone Cue Monitor with Traktor DJ Studio (using the headphones to monitor the next song you are going to mix, like DJ's do). Maybe I'll save a few bucks for a Chaintech AV-710 in January (after I recover from the blow of buying my new computer - see sig).
Hope this helps.
Cheers.
