There are some problems with high DPC latency on most Gigabyte boards released since P35 upto X38/X48. Some people have the problem and dont know it.
You can check by downloading DPC Checker from here:
http://www.thesycon.de/deu/latency_check.shtml
DPC's (deferred procedure calls) should be around 50 us or less without any spikes on a normal PC.
Regular spikes upto 1000us is not good and any higher into the red will result in audio dropouts and stuttering of streaming data.
Its mainly affects people who do things like audio editing on the PC but it can be a problem for anyone, even affecting system responsiveness .
Gigabyte have acknowledged the issue and have released a beta bios for some P35 boards but you have to contact them and ask for it so if anyone has run the checker and has problems , i suggest you contact Gigabyte tech support and report the issue.
Many "slow Vista" complaints can be traced back to this issue and you can check if its having an impact by opening Event Viewer/Applications and services logs/microsoft/windows/diagnostic-performance/operational.
You may have a bunch of errors and warnings complaining of "system degradation" "boot degradation" and other related issues.
So if you have regular spikes in the DPC checker report it to Gigabyte so they realise this is a widespread issue and it needs to be resolved quickly.
Also maybe some guys at Anandtech can look into this problem please.
