Need to connect my 5.1 Creative speakers with My Acer D250 Netbook

Hi guys,

I am having Creative Inspire T6100 5.1 speaker system

I need to connect this with my Netbook acer D250

I googled and find i need to get some sound cards to experience the real 5.1 surrounded from laptop/netbook

I have found Creative SB X-Fi Surround 5.1 sound card but its costs 3400rs

Is any other sound card is available like this which is bit lesser compare to creative

Please suggest

Thanks
