why get the 32 bit when 64 bit is actually $5 cheaper and it can take advantage of all 4 gigs of ram plus some, if you find it necessary to buy more...
I've got both home premium 64 bit and home premium 32 bit on comps in my household, and there is absolutely nothing that puts the 32 bit above the 64 bit, just follow the link and get the 64 bit
also, I'm using a proxy to post... I'm still a script hacker, LOL
