that's true but I'm not asking the differences i'd get in mhz - speed , just if having a bigger amount of cache would help or if it's not much important for mixing stuff with a bunch of plugins active... even a 2180 can run at 3ghz properly cooled
the "real" question is : how much does the amount of cache memory influence the performances of the cpu in this specific task?
sorry, I didn't make this much clear at first...
