Thanks all, especially Lu-tze (sorry I don't know how to get the accents on your name).
Unfortunately after checking my mobo manual is apprears I need a CPU that fits a Socket-462 socket and none of the athlons I have seen on the sites suggested would fit. Looks like I will have to upgrade my mobo as well :-(
thanks village one more question save me staring a new thread if john harvey does'nt mind, is it ok to just change a cpu when it's already fitted to the mobo as in my mobo manual it says to fit cpu before fitting mobo hope you understand my question. thanks deep
