Yeah, no problem. You've got some pretty serious hardware there. I was trying to compile from a 433 mhz processor and it was painfully slow, and my 56K dialup connection made it even worse. You won't have any problem, but you will have to learn how to set "Use" flags (and a few other things), if you want to gain real efficiencies and speed over people using sabayon's binary package manager. Even then, it won't be huge, in most cases.

for the "spin base" version. I don't know if that's what you want, but that's all I know. Have fun!
