I've been hearing that the lag is experienced ONLY by those with the fat (aka old) PS3...i have a 80GB PS3 (old, maybe umm 2 years, i think i bought it before slim was branded) and i really can't afford to buy a slim one...how is this possible (the lag on fat and not on slim), since both versions share the same hardware (slim being smaller though)? I'm so worried...sigh
Could some one, with old PS3, say have they had any lag so far and such? i would be so happy if you guys could help

Thanks in advance
PS: Sorry for a messy post...lol
