I think they should make something like an FX 4130P (I assume P = Performance) that has 8 modules, but only uses 1/2 of each to take advantage of all the potential bandwidth heh (John mentioned that on the 20Q blog, that a thread on each module would yield more throughput then two threads pers, but would produce more heat since modules couldn't shut down.)
I'd consider buying that, if they'd overclock into the 4.5GHz area almost guaranteed :)
