I'm going to be switching countries for work (one month in Brazil and one month in the US). So I'd like to bring along a laptop armed with some analog softsynth VST's and a Roland FantomX6 to keep me sane while in Brazil. I've never used softsynths so I'm really in the dark here. I'll be running SONAR on the laptop. Softsynths I'm looking at are ImpOSCar and Arturia's CS-80V since that is one of the all time great sythns; plus that Vangelis guy seemed to like it a little so it can't be all that bad.

Maybe one of the Arp 2600's or a Minimoog clone?
So the main two questions to the softsynth/VST gurus (AnDrOiD... RU out there???):
1.What are the best analog softsynth VST's out there to take along with me. Will they really give me (or close to it) that analog edge taht I'm used to and most importantly... I've heard that some can be really intense on your CPU.
2.What specs should I be looking for on a new laptop (processor, RAM, soundcard etc.). I can spec my own laptop and buy it that way. The only stuff I'll be running on it is music software, SONAR, Soundforge, Acid, whatever Softsynths I choose to buy. Sorry so long winded but just wanted to let you guys know what I'm looking for. As usual... thanks in advance!
BTW... before asking, I thought about just going laptop with full aresenal of softsynths or switching to Reason with a midi controller; but I really do like that Fantom-so why not just the Fantom? I'm a greedy little bugger and want more analog sound
