RazorEye: Recently had an experience that affected using soundcards that is an eye opener. First I use headphones for 2 of my rigs. I have Logitch G35s and since the soundcard is built into the headphones and it hooks up with USB only I could do away with the dedicated add on sound cards.
Most importantly, on rig three I was using a Creative SB X-Fi Titanium Fatality Pro a really nice SC. I upgraded the MB to an Asus Sabertooth 990FX and wanted to run 2 460GTX video cards in SLI. The PCI-E slot was not accessible for the soundcard so I am using onboard sound with the same Realtec ALC 892. It is VERY good. My speakers are an older Dell 5.1 Surround sound system with 4 smaller speakers, a bass and a central control unit. Hardly a "high end" speaker system. The sound is great from the onboard chip.
