64 Bit Windows with 2GB RAM??

Hi, i am thinking of getting a small notebook for school purposes but i see that they are coming loaded with a 64 bit copy of windows even though they only have 2gb RAM. Will there be any performance issues using the 64 bit version instead of the 32 bit version? Or should i reinstall a copy of windows i have using the 32 but version. Thanks
 
I would check that you can add more RAM to this system as 2GB is pretty low these days and you will encounter performance issues. Don't get me wrong, sometimes it will be OK but other times it will hang and crash. I would say 4GB is the minimum to be looking at.
 

Yeah, the issue with a 64-bit OS with such a marginal amount of RAM is that program data structures that only require 4 bytes of RAM (e.g. long integer) end up taking 8 bytes. So with the exact same programs loaded and doing the exact same thing, the 64-bit OS will run out of RAM faster than the 32-bit OS.

The OS itself won't cause a performance difference (in fact the 64-bit version will be slightly faster if you run a lot of programs which use 64-bit data structures like double floats). But the performance slowdown will come when you start to run out of RAM and Windows starts swapping to the pagefile.

If you get the notebook (I wouldn't - the minimum I recommend for Windows is 4 GB), I would suggest downloading the 32-bit version of Windows and installing that. The keys are interchangeable between the 32-bit and 64-bit versions.
