Ok. so... I just want to be clear here. Let's say that the fusion drive issues of yore have been addressed (and from the bit of research that I've done this seems to be the case). Moving on to the dual vs. quad question. I know that it's usually preferable to have a quad, but would the dual core cpu in question be enough to run LPX plus some things like instruments, plugins, etc? Also, is there a problem with 8gb RAM?
