motherboard with DTS CONNECT/ dd live

[Pioneer]

I´m searching for a motherboard with DTS CONNECT/ dd live (costs: 250$), 1366 base (don´t what "Sockel" in English means, hope you understand it).
Or is it beter to buy AND cheaper to buy the cheapest motherboard and a soundcard?

Win7 supports Dolby Digital Plus (basically a newer DDl),you can also look for something specific with Dolby Digital Live.
Various DTS versions/formats (like NEO5) is often included with the on board audio (like the newer Realtek 892)
