I have a friend with the 4.1 Klipsch ProMedia. Scared the crap out of him when he was playing Undying and the subwoofer blew a paper bag from under his desk
Unfortunately I just bought a MSI Neo 4 Platinum, A64 3000, x800XL and there is not much left in my computer upgrade budget.
I have enough for maybe an Audigy 2 Value and better headphones or $150 speakers, but not a Klipsch 5.1 system.
I still havent gotten an answer about the 3d sound?
I think that will be the deciding factor for me. If I can hear where sounds are comming from better with 5.1 speakers I will get those, if the headphones work equally as well then I will go that route.
