This a great machine, but for the same price (slightly less), you'd get a
a desktop machine (also from apple and therefore definitely not cheap)
4 cores at 2.67 GHz, just for example.

...Are you really sure you want to do these on a laptop?
Laptops tend to run hot under heavy load; they are mobile (and built for
being mobile), but you definitely shouldn't move a laptop running a long
MD simulation around, they seem to be easily broken (though I seem to have
been lucky in this respect till now) and expensive to fix; Laptops
generally offer a bad "bang for the buck ration".

For the price of the above machine, you could get a decent quad core
desktop machine (core 2 duo at 2.66 GHz) plus a laptop, which is still
fast (for everyday work and all but the newest computer games) and still
have some money left.
