Things like these are driven by budget. Post your budget and people would be able to help you out. Most audiophiles would suggest you a good 2.1 or even a 2.0 system and upgrade later on.
Brace yourself for big time movie thrills, right in the comfort of your home. With cinema-quality multi-channel surround from 5.1 to 7.1 surround and support for both DTS-ES and Dolby Digital EX you'll enjoy movie audio the way the director wanted you to hear it!
if you are thinking of using your PC for surround, my recommendation would be Logitech X-540.
