that tells us it is a Newcastle core.
Newcastle's are the second core revision of Athlon 64 CPU's. a new core revision is an improved version of the previous core.
swapping out the CPU is easy, you just have to be careful not to bend the pins.
also, you need to make sure your motherboard is the right socket first.
you need to take off the heatsink, put on the new CPU, and put the heatsink back on (or put a new one on)
the most important things are: not to force the CPU in. the socket is called ZIF (Zero Insertion Force)
also, make sure the ehatsink is on properly. if it is not, the CPU might overheat.
