I am buying an Alienware MJ-12m 7700 notebook and have some questions:

It comes with a Intel? Pentium? 4 Processor 530J w/ HT Technology 3.0GHz 1MB Cache, is that good/bad?

What changes would I notice if I upgrade the processor?

If I have 2GB RAM instead of 1GB RAM, will it increase the speed of the computer or just allow me to run more programs at the same time?

Is 2GB necessary?

Harddrive:
60GB 7200 RPM ATA100 [+?61]
60GB 5400 RPM ATA100

A 60GB is enough for me but one is more expensive, what changes would I notice if I got the more expensive one?

Finally, which graphics card is better, and what changes would I see if I got the better one?

NVIDIA GeForce?
FX Go 6800 256MB

or

NVIDIA Quadro? FX
Go 1400 with 256MB

All support is greatly appreciated,

Shyam
