I'm about to ask another frequently asked question. Will my specs be able to run it decently? If yes, only then I'll purchase the game, don't want to waste if my PC cannot run it smoothly (or have to turn the graphics to low).

AMD Athlon64 X2 7750+ (2.7GHz)
4GB RAM (Actual is 3.2GB due to 32 bit OS)
ATI Radeon HD4850 512MB
