I built an I7 3770K machine last year. It just screamed. BUT... Sonar would just stop every 1 to 3 minutes. There was no obvious reason and I had to do research. It had to do with CPU latency issues. IF you have problems, look at turning off the wait states in the BIOS. Once I did this, everything worked great. Now, realize that I push it REALLY hard. I record 32 tracks live at 176kHz sample rate.
