Creative Sound Blaster X-Fi Titanium Fatal1ty Professional 70SB088600002 7.1 Channels 24-bit 96KHz… for $89.99
You WILL hear a difference from an Audigy or older CL sound card or an on-board sound chipset.
This usually lists for $149.99 with an occasional $30 rebate, so $89.99 is a pretty sweet deal. I've only seen this added to the annual CL sale once before since this product was released.
For my location, it is listed as $8.26 shipping.
