Mac OS X OS Version Support (Currently Leopard and Snow Leopard PPC and Intel)

[Nothinglikesleep]

I'm in the same boat as Bulbatron, so if I'm confused I'm sorry (specs and OS for 21.5 iMac):

Mac OS X version 10.6.3 Snow Leopard
3.06 GHz Intel Core 2 Due
1920 x 1080 Resolution
4 GB memory
500 GB hard drive
8x double-layer SuperDrive
NVIDIA GeForce 9400M graphics

I want to pre order but not before i know if i will be able to run it. If a developer should happen to see this (or gamer) when they find out more about Amnesia requirements please comment on the above specs as to whether this mac can handle the game (even if special effects need be lowered). It handled Overture and Black Plague okay.
