I just think both the FX series and the EE chips are way overpriced for what you get.
By what you have said you are planning on overclocking. Why not just get something like an Opteron 165 and OC it to FX-60 speeds? Most are doing that easily and they are less than half the cost.
On the Intel side, the move to 65nm did give their dual cores a good boost, but it still lacks in some ways. However, if you do look at that thread I linked to, many of the 9xx series chips are going close to as far as the 955 and again are way less expensive.
BTW, those overclocks in those reviews are kind of lame. They OC'd by upping the multi only. The P-D's are fairly bandwidth starved and going big on FSB adds much more than just upping the multi.
Edit: Example, here is a 930 at 4.6Ghz air cooled. Check the price of that compared to the 955.
