Hello there. I notice at my collage i can buy windows 7 pro 32bit and 64bit pro for $40 Cad. this is legal copy of the OS. Full version not a upgrade. I am wondering if i should go 32bit or 64bit? what do you think? my pc is custome build and has a intel mobo. I have a intel q9650 which runs at 3ghz and is 64bit chip. 4 gb of ddr 3 ram , ati 512mb 3870 and 300gb wd raptor hard drive which runs at 10,000rpm. the man program i use is dragon speak 10 pro which i use to do my home work for school and photoshop cs3 and office 2007 and some games. I have legal copy of vista U 32bit on now. also what is the diffrence in 32bit and 64bit of 7 besides the ram. thanks for the help.
