Why just not continue on your previous post? ?(
Why can't you just google this in first place? that's what I did with newegg and that link in your previous post.
I am certain there dozens of websites that reviewed this topic dozens of time, and more thoroughly then can be worded in few sentences here.


PS: Google: 32 bit vs 64 bit vista and vista home vs ultimate <<< that's all I am willing to do for you.
sorry if I am too harsh, but try it yourself a bit.
