AFAIK, any dual or more core Core-series of 3.2 GHz or more should run Blitz full speed (possibly with occasional slowdowns on the lower end of that range). As always, you can get a good idea of game speeds from John IV's MAME benchmarks.
If you're looking to do a relatively extensive upgrade, wait a month or two for Intel's codename "Sandy Bridge" processors - they use a new socket so you'll get a more future-proof build then. (And they should be a bit faster per-clock than what's out now).
