Right on AMD being mroe better than Intel...  But what I was getting at

I used to have a single core 3200+ (2200 MHz and 512 kB cache) in my
ASUS A8V Deluxe.

I then put a low-end X2 into it (also 2200 Mhz and with 512 kB cache)
and my build worlds are now twice as fast! :-) SMP does have its benefits.

The only drawback was that I had to replace my RADEON card with an
NVIDIA due to stability problems in SMP mode. Since I run mostly in
32-bit mode the nvidia-driver port works OK for me. However, that
would not be an option in 64-bit mode!
