Does anyone have any recommendations for a midrange sound card? I'm looking into the Fortissimo III 7.1, and I currently have Logitech Z-540 (4.1) Speakers with the Realtek AC97 Audio (Supports EAX) on a KT333 mobo. I was considering an nForce2 with SoundStorm, but I'd rather not have to reformat, and it's out of my budget. I'm willing to spend $40 to $80. Thanks!
