How much RAM are you getting and what are you planning to run in Windows?

In most cases 32 bit is probably going to work out better.
 
Thanks tyr2,
i have 4gb ram already on my mb. I intend to put some biological softwares designed exclusively for windows and some other softwares (which tend to be cheaper for windows version and a lot of offers also tend to come up for windows users) and also sometimes to browse online music stores which support only windows.
