Well I guess you need to know the mother...I had to replace my motherboard recently and got ASrock Fatil1ty 990fx Killer. It has the Realtek ALC1150 with purity sound (marketing hype I am sure, the purity sound but it does sound a lot better then my old sabertooth 990fx r2.0 when the sound worked). I had bought a soundblaster REcon 3d Pro in old motherboard when the sound went out as I did not want to do yet another motherboard RMA at the time. Another issue recently arose so I got this motherboard. Not sure if this information is needed or not. CPU FX 8120 mild OC to 4400 Ghz, 20 Gigs ddr3 1600 ram (13 gig for ramdrive)(mixed ram 2x8 and 2x2 dual channel), Windows 8.1 update 1, AMD HD 7770 x 2 (factory OC) I use a set 5.1 Logitech z506. Used for online gaming, home music, and movies. Yes this was a budget build as I am on disability so have to plan wisely. So the question is should I use the ALC 1150 or the Soundblaster Recon? I have unlocked the Dolby Home Theater in the ALC 1150 Onboard or I have THX on the soundblaster.
