Hey guys, Im kinda new to the building of a computer aspect. Currently I am upgrading my computer and I was wondering for the proccessor, What should i be looking for? or what should I look out for keep in mind? Does it matter if my computer is a 32 bit or what? and for upgrading the hard drive, if I go up from a 32 bit to a 64 bit, do I need a new motherboard? and if I get a new hard drive, does it come with an OS on it? All the help will be appreciated thanks
