Win7 64 bit

HI
I am ordering a new laptop for my RS programming…and i would like to know if I can have any advantage of buying win7 64 bit instead of 32 bit version…here are some stats:

Intel core I 7-820 QM quadcore 1333 MHZ ( MB cache)
8 GB Memmory
1GB Nvidia quadroFX1800
128 GB solid state HArdidrive

I want maximum performance so please advice??

A 64-bit operating system allows Robotstudio to use up to 4GB of RAM instead of 2GB on a 32-bit system.

In other words, if you regularly work with large CAD geometries and have a machine with at least 4GB of RAM, then a 64-bit O/S will definitely be the better choice.
