hi after some thought ive dcided im probably gonna plump for the logitech z-550 5.1 speaker set to use with my laptop. However because im using it with a laptop and my onboard sound card aint great, it also means im probably gonna need a new external soundcard - any suggestions? I've looked at the creative audigy 2 pcmcia one but have heard it can be difficult to connect with speakers that aren't made by creative? Im a also feeling a little reluctant about going for a usb one as ive heard they cant handle the data stream and can only recreated dolby eax and dts through software rather then hardware. any thoughts or ideas would be great. my laptop spec is: p 4m 2.4ghz 640mb ram 60gb hard disk geforce 4 440 go 64mb on board sound usb2 and firewire ports im looking to spend a max of around £100 on the soundcard.
