The last DAW I put together uses a 3.2 meg dual core 800fsb 775 socket. I have everything tuned as per
this
The 1.6 will be adequate with the above tuning, proper and enough memory. (I did run a 1.2 for a year or 2) The other CPU I am not familiar with..
MOBO
With Roxbox and sonar3 running the cpu usage runs less than 5%. On ocassion I have run several tracks in Sonar with no problems.
I have read posts on HR from the experts not to use dual core but I have never had any problems.
The secret to using Intels Use enough heat sink compound on the heat sink and make sure it is flat and tight on the CPU.
