@ "Iwant a laptop" ARE YOU KIDDING ME? Spend the extra $30 and get a Pentium Dual Core E2160. Those celerons are a SERIOUS NO-NO! DONT GET A CELERON. PLEASE. ITS A STUPID PURCHASE, the Dual-Cores are almost the same price (just ask Google "shopping") get one of those.
i know celeron's have improved greatly, but they still don't stack up at all to a Pentium Dual Core (and no i dont mean PD, i mean the new Pentium-Dual Cores, which are basically underclocked/stripped down Core2Duos).
Heres an E2160 at $55.
If you really wanna overclock, you're gonna need a better mobo and ram (probably), but if you do indeed do that, you'll see the E2160 is one HELL of an overclocker (it can beat an E6700 when its at 3.2).
even if you dont overclock, screw the Celeron - and get the Dual-Core.
