are all processors such as the Intel Core i5-3570K a 64 bit?

All desktop processors since the second half of the Pentium 4 era have been 64 bit, almost any modern processor you find will be 64 bit, there are a few Atom based chips that are not. All of the core 2 duo, and Core i series CPUs have been 64 bit.
