What is My Cpu ( x86- x64 )

[Fallensegal]

I am completly clueless..

I just bought an a8-6600k and I need to know which one it is so i could install the right os...

( I have the product key but i need the actual program so i am creating a bootable disc )

It is 64 bit capable. How much RAM do you have?
