And after realising that Bootcamp doent format the new partition all is going well, however Windows seems to be stealth hammering the machine, battery life is almost half what it was in OSX and the machine is getting very warm.
The machine isnt doing much atm, jsut coping files over the network (Wireless) and the CPU is idle so I can only assume its the GPU.
Now I read somewhere that on older Macbook PRO's Apple clocked the GPUs right down to get more battery life from them, is this the case with the Unibody macbooks and Windows is just running it at its default speed?
