Yup, correct about the
x86-64 extension set [wikipedia.org]. Don't worry about all this though hayper. For all intensive purposes, x86 = 32bit and x64 = 64bit. Its up to you which one you install, your processor is perfectly capable of both. 64bit has come along way in recent years, I would give it a shot.
I say extentions, some say it's true 64bit, some say other ****. If it runs 64bit code it is 64bit, but who cares. =P I just say it that way because I don't want to start the pure64 battle...
hahahaha
friends i instal the 32x one... and i'm enjoy in it... i tought the x64 will be compicated from x32,,some programs must be for x64 then and i wounder the some games will not work on 64x...
