Hi Royce,
Eh, since N3 isn't finished yet, nobody knows for sure. Whatever the
specs are, I'm sure that it's cheaper to upgrade when N3 is released.
For an indication, wait for the release of GPL. The min specs
shouldn't differ much, I reccon.
BTW, NEVER upgrade BEFORE a game is released.
Cann't help you with that, sorry.
