http://usa.asus.com/mb/socketa/a7v333/overview.htm This is my new motherboard, which I'm installing on the 25th...at the moment I have a crappy SoundBlaster 128 (stereo) sound card. Should I stick with that, or should I use the onboard sound [is it dolby 5.1? ]? If so, what speakers should I get? (under £70 please) Is it worth using the onboard sound or should I save for an Audigy 2? BTW - will one reduce system performance more than the other? Thanks.
