Overclocking is mainly making your component to run faster from its intended speed, while how much it can overclock, it depends on your component quality, some can overclock higher, some can't even overclock.

For CPU, their clocks is determined by multiplier and FSB (C2D)/ BCLK (Core i3/i5/i7)
e.g. C2D P8700 = 9.5 x 266MHz = 2.53GHz

Since for most CPU, their multiplier is locked, except the extreme series, we can't do anything to it, so the only option is change the FSB/BCLK to higher MHz..
e.g. Core i5 450M with 2.4Ghz is 18 * 133Mhz, we increase the 133MHz to 160MHz, then we achieve 18*160Mhz = 2.88GHz, which brings it faster speed than i7 620M
The risk? Higher temperature and unstable machine if you overclock too much...
CPU dead is almost none since we are not playing with voltage in this case...

i dun advise you to overclock a laptop if you have no idea whats up with it.....considering you have totally no idea now. and 3k-8k is an extreme difference in budget. you can get a 3k laptop working just like a 8k laptop. if you are seeking for performance, vaio Z is not what you are opting...its the highest end in terms of exclusive and class in laptop region. if will be funny if you want the laptop for performance on the go..........as vaio Z had been advertised as an exclusive product for impression. just like mac books and fujitsus.

lets make it simple, vaio Z will be a good choice for businessman to show your standard in front of your customer. during presentation. its the ultimate weapon because of the carbon fibre touching. material of aeroplane on your hand, get over by a car but still able to work as normal and almost 0 problem occurs with it. by paying double or triple the price tag of another laptop with the same spec.

if you are seeking performance or performance on the go. performance never go with exclusive. you can get rm3k laptop with the same performance, then the remaining rm5k, change to a better laptop for rm3k next year, and 3k next  year. next next year a rm3k laptop is equivalent to a rm5k laptop this year.

considering you know merely anything in the details of hardware, i guess ur friend suggested you to buy vaio Z. it REALLY really boost your social status. thats for sure. its just like buying a rolex that can give you time just like a casio. the power is in your hand.

and i doubt you game or do something graphic intensive? so gt330m should suffice.

i think for your case, you should aim vaio Z, fujitsu business class, lenovo thinkpad X, vaio Y, dell latitude or adamo....these laptops are business class, they dun have those monstrous spec young gamers want at reasonable price. but they offer tough cockroach lifespan and build quality. they do cost twice the price of other laptop but you get less hassle. you can still do your daily chores at a business class level. =D

Z13x coming up soon with new processor

Better install the update, you never know what kind of security hole left in your windows...

Wah... congrats... finally get your VAIO Z...

all laptops with DVD/BR Drive are class 1 laser product... coz if no laser then cannot read DVD lo.
