I've got 512 RAM ATM (yeah, I know, it sucks ) and for stuff like photoshop it starts to lag a lot. And after playing BF2 it takes ages until it gets up to speed again.
BTW, the only thing what could happen is that you fuck up the HDD. And then you could just connect it to a PC and get a fully clean again.
Anyway, I'll read it now. And maybe that guy played old games you know or he's just blatantly lying.
