I am building a mid-range gaming system based on an MSI P35 Platinum MB. That board has an on-board hi-def audio capability based on Realtek ALC888 (7.1 channel surround sound up to 32-bit/192KHz). I have a Creative SB X-Fi platimun sound board from my old system. Is there any benifit to using the Creative board over the built in Realtek audio save for the X-Fi capability, or do I eBay the X-Fi and save the PCI slot?
