Thanks for the replies, Rounik and Gary.
Actually the guitar lessons are a labor of love anyway since it's such a good friend. I would have done it for free. Cold hard cash is wayyyyy harder to come by, so this is, by all accounts, a screaming good deal for me.
I will definitely be in 64 bit. I hope to put 24 G RAM in there too, to take full advantage. All my plugins are 64 bit except Soundtoys, which is a shame because those are some of my most used plugins. Apparently they've been working on the upgrade for awhile now.
The 32 bit bridge server always crashes and is just annoying!
There other question that I have is should I put apple or third party RAM? I figure why not third party, no warranty to void anyway since it's a 4-year old used product. What do you think?
To Rounik-
I'm moving from producing commercials and voiceovers to making dance music, at the moment. That looks like 25-40 tracks for most projects, and I use multiple instances of kontact strings, razor (very cpu hungry), several less hungry synths like sylenth1, and a lot of logic internal synths, including sculpture. For drums and most samples I use Maschine.
Hopefully I'll be fine processor wise!
