I’m in the market for a new laptop – well, used actually. There are a couple that I’m looking at. Both are the same model Dell with a 250 gig HD and 4 GB RAM. The difference between them: One has a 2.93 GHz processor and is loaded with 32-bit Windows 7 Home Edition. The other has a slower processor, 2.66 GHz but has 64-bit Windows Professional. Would one of these be better than the other, and if so why? Or is it a wash?
