I'm about to build a new gaming PC and would like to know what the real performance difference is between the Audigy ZS and the leading onboard solutions from Realtek or Nvidia.
Although I found many reviews of the Audigy ZS card, nearly all of them only say "low CPU Utilization", but don't give specifics (lazy reviewers!). I did find one site with Audigy ZS Benchmarks that show CPU utilization to be 8% - 16% using the RightMark 3DSound benchmarking tool. (The reviewer said that 7% of that CPU utilization might have been due to things other than audio, so who knows....)
I also found a HardOCP review of an older ABIT motherboard that says "there is < 1% CPU utilization across the board while using the onboard Realtek based sound subsystem"
So does onboard sound perform just as well (or better?) then the Audigy ZS? I know Audigy ZS
sounds better but I only care about games (not music or movies) -- and I wear headphones 90% of the time, so I don't need 7.1 channels. I keep hearing (on all the hardware review sites) that Audigy ZS has "lower CPU utilization", and so I want to buy one because CPU utilization is important to me. But will I really get lower CPU utilization from the Audigy ZS, or is it all lies?
