EVGA x58 Classified, Samsung F3, Auzentech Forte, 5870, Win7 x64. The latency is jumping around a lot... Usually around 70-150us, but sometimes jumps to 500-1000us! :o
I am not experiencing any issues, though. I tried changing the mouse and it made no difference whatsoever. I think it's the audio card, it's buggy sometimes. Oh, and I need a reinstall, but doubt it's the case.
