Yes, I must insist that if you have the cash for a 4000+, it would be better to invest in an FX-53 or FX-55, basically the same clock speeds, but double the L2 cache.
Edit - hmm, I've just realized the 4000+ also has a 1MB cache, interesting. =/ I would still recommend the FX series though, although either processor will perform bloody fast.
