The 3970X is basically pointless anyway. It's just a 3960X clocked 200Mhz higher...
Anyway, I would just get the 3930K, if you really need a 6 core powerhouse like that.
The 3930K is only 100Mhz slower than the 3960X and otherwise basically the same (the only difference being how far you can OC. I forget how many "bins" difference there is, but it's nothing that you would ever need to worry about, since the 3930K can OC higher than you really ever could with normal cooling, anyway).
