The DA5000 Pro in that link is overpriced , you probably should be able to source one for around 9k , i myself overpaid 11,400 . Having said that i would recommend you to buy a 2.1 setup unless you really want to go for a 5.1 surround sound which is supported by few pc games out there , but you will need digital input (coaxial , hdmi) to get 5.1 output of a home theatre system so connectivity wise iw ould recommend to you z906 at that budget.
