I'm looking at getting a medusa 5.1 headset (the non usb version), and whilst reading through opinions on various forums, such as overclockers there seemed to be a general opinion that to get the best out of sound in games such as counterstrike it was worth paying for a separate sound card such as a Creative Sound Blaster Audigy 2. At the moment my soundcard is inbuilt (see below for details). Is it worth paying the extra for a sound card? At the time I built my system people said it wasn't worth getting a separate card as the ones built into modern motherboards were just as good for gaming. If its worth getting a seperate what is the difference between the Creative Sound Blaster Audigy 2 Value 7.1 PCI Sound Card - OEM (SC-027-CL) and the Creative Sound Blaster Audigy 2 ZS 7.1 THX Sound Card - OEM (SC-023-CL) at this link. http://www.overclockers.co.uk/acatalog/creative_soundcards.html MSI K8T Neo-FIS2R Integrated Hardware Sound Blaster/Direct Sound AC97 audio 5.1 - 6 channels software audio codec RealTek ALC655 - Compliance with AC97 v2.3 Spec. - Meet PC2001 audio performance requirement.
