Get the best system you can afford, and I think the 160GB PS3 is the best money can buy..... Otherwise the 80GB is more than good for the next 5-6 years
PSN ID: T_Gears
End of 2009 ltd sales:
Wii = 67-68m
X360 = 38-39m
PS3 = 34-35m
Prediction: The PS3 will surpass the 360 on weekly sales after it drops to $299 on all regular weeks (no big releases).
