Overclocking is not recommended on laptops as you cannot upgrade the cooling and its never very good in a laptop to start with. As any overclock would be quite small due to the cooling limitations I would think you will not get much of a frame rate improvement. Also the 5850 mobility is a slower clocked desktop 5770 (sometimes with slower DDR3 RAM) so the i7 is unlikely to be a major bottleneck for it. If you do overclock the processor disable the hyperthreading as this makes it run alot cooler and games are unlikely to get an advantage from it.
Thanks for the heads up Simon.
Ok, so I will not think about overclocking the 5850.
You say the i7 can be overclocked but to make sure hyperthreading is disabled. Ok. Will i get any significant FPS boost by overclocking it but not having hyperthreading enabled?
How dangerous is overclockinhg the i7? I'm a noob when ity comes to overclocking and the last thing i want to do is ruin my brand new laptop.
