Hello im wondering if it would be wise to upgrade to windows 7 64 bit over 32 bit. I have Vista 32bit on hp laptop with 4gb of ram and a core 2 duo T8300 processor. I can get either version for like 8 bucks through school so my last decision to make before i buy is 64 or 32 bit. According to hp's driver support site i can get basically every driver i need in 64 bit so that wouldn't be an issue. Ive heard that the 64 bit version isnt as useful with just 4gb of ram and that it could be slower and use more battery life than a 32 bit OS. Any suggestions?
