The CCC in just a notebook

[LMG]

I was thinking of buying a notebook to run the Comple Composer's Collection. An option is tu buy one with the following components:

OS: Windows Vista® Home Basic Original SP1
PROCESSOR: Intel® Core™2 Duo T5750 (2.00GHz/667Mhz FSB/2MB cache)
HDD: SATA of 160GB (5400RPM), plus 2 external drives 160 gb (7200RPM)
MEMORY: 4GB Shared Dual Channel DDR2 at 667MHz
SOUND CARD: M-Audio Fast Track Pro (external)

Will I have many problems running big scores (full orchestra) with CCC in this machine ???

Thank you!!!
