I will be running a large tekkit server, hence the 32 GB of ram. I will be using a surround sound system, which is the only reason for a sound card, I also do audio editing. The 830 may be cheaper but I've had great experiences with OCZ. I would get my 3570k from microcenter, but I don't have one near me. But thank you very much for the criticism it helps with the final product.
