What is it with people ignoring simple instructions.

1)
Cores first, then speed. More processors is just more cores really, but the IPC is slower so those cores on the second processor take a performance hit.
2) SSD's make projects load faster, as a system drive they don't make a huge difference to the power of your Logic projects until you start putting the latency of your sound card into very low ranges. Again at this point you lose a lot of processing capacity and you start having to use the Low Latency button a **** of a lot, so to put it simply... it makes things feel faster but it's not actually giving you more power 99% of the time, if you have to scrimp to fit a budget this is the first thing I'd cut.
3) 32GB I would say, but it depends on usage. Before I bought Vienna Symphonic, I would have got away with 8, maybe 16 on the occasional project, but then I use a lot of synthesis in the genres of music I work with. And 3rd party, every time. Hynix and Samsung RAM are cool (it's what Apple use), but there are unlucky folks out there with far less trusty brands of Ram coming out of their systems. I like Mushkin and Crucial, and have had problems with Corsair and Kingston, but the latter two are sweared upon by a lot of users here. The common thing here is that almost nobody upgrades via Apple unless they must.
