nope does not have one .. I was tempted to try it .. but probaly not really worth it for the amount of work I would need to do. with those specs you should run basicly all games fine with out a 32bit core? 32bit core is only good for speed, and with comptuers getting faster it is just helping the low end machine ..so it is a short term bandage .. if you really have a low end machine there is always corn, uhle, and 1964 does a good job to.
But I do not see why you have speed issues unless you like running above the default ?
