Hardware choice

As far as i understand, ram capacity is the vital solution to increase software performance. If i choose a Intel® Core™ i7-3840QM Processor to run carpark ventilation simulations, will it provide a 64 or 128 gb ram? because it says max. memory capacity 32 gb. In this situation, should i change the processor type?
Xeon will be ok? and one more question, is 6 cored processor really multiples the performance compared to 4 cored processor?

First the i7-3840QM is a laptop processor I would recommend against doing CFD on a laptop. Second you only need as much ram as the problem requires. If you programs needs 2 Gb to run having 64 Gb won't make it run any better than having say 4 Gb. Also I think the regular ivy/sandy bridge chips only support 32 Gb. The sandy bridge -E and the XEON chips support more. Ram speed tends to be more important. As far as the scaling goes you need to specify more about the software you are using, some codes scale well others don't.

i didn't notice that 'Intel® Core™ i7-3840QM was a laptop processor. i put it to show as an example. i'd like to choose the memory capacity as high as possible. because i can not foresee how massive could the carpark be.to be honest i am trying to use FDS to analyse such building carparks. But, the main software is ANSYS. Will i7 processor (with a 32 gb memory capacity) be enough to execute such analysis?
