I just got Helix native. It sounds great but man did it good cpu. 4 instances was all I could pull up, and that's with one instance of ezd.
I usually have a ton of tracks... 10 of bias fx and other virtual instrument and never any problem..... I'm on a Windows machine i5 4670, 8gb of RAM.
Will additional ram help or is it the chip from and i5 to an i7?
