Hi Ben,
The CPU question basically comes down to the question whether the processor (RAM memory) will require a higher performance. Having said that, Analog Lab and CS-80 run okay on my device, a Macbook Pro. But maybe, because the V-collection is such a big package, it might not meet the requirements for optimal performance?
Maybe I should first install the trial version to see how it goes.
Cheers!
