About the memory, MS has arbitrarily placed an artificial limit of 4GB to the RAM for 32 bits systems. This may bring problems for getting the full amount usable, often you'll end up with between 3.2 or 3.5 GB really available. 64 bits Windows has no such limitation, and can recognize an use the full amount (minus possible on-board video cards that draw VRAM from system memory).
Often 64 bits systems are more memory-intensive than 32 bits counterparts, but again, this is many times not too important to make a difference.

I have no clear recommendation, at least without knowing the use you plan for the computer. For the most typical users, it don't really matters that much, and both will be fine.
thank you for your reply,
well I am using computer mostly for CAD software

I always install 32 bit on 4gb RAM or less. It performs better.

You can see exactly how much RAM is apportioned to hardware so you'll know that you are using everything above 3.4 gb which is all 32bit can use for the OS without modification. Type "Resource monitor" in Start Search box, click on Memory tab.
