after burning out 2 laptops in 3 years, id go for a desktop
On one, the onboard video fried, resulting in a new motherboard
on the last one, a hp dual core massive motherboard failure due to
insufficient cooling.
my advice, buy the components:
motherboard
cpu's
HD
ram
psu
and case
and assemble your own! works out loads cheaper than a factory built contraption, will be much, much more upgradeable, and faster if you select the right processors.
oh! and cooling lol, dont forget the fans !!!
