Hello. I am going to upgrade to Windows 7 Ultimate from Vista Basic 32 bit. As said in the title, I am curious if I should go with 32 or 64 bit OS. I do alot of gaming on my PC so I would like to have which ever one would increasing performance. I would appericate your opinions on what I should get. I am aware that my processor can support 64 Bit OS. I am also aware that 64 Bit can read more RAM, but I have been hearing from some people that 64 bit would be better and the same for 32 bit. Thank you for any help.
