I've had good experiences with P4 (with and without HT), Athlon64, Xeon
[dempsey], Xeon [woodcrest]. The last one is the best choice because of
the large cache and architecture. I think you can use Core 2 Duo too
if you want to save some money.

Thanks - I will see what I can get

I used AMD Opteron 2Ghz and it blazes. In my packet switching 

benchmarks, onchip cache gave no benefit. On price-performance basis, 

you'd be better off going for greater CPU speed than for cache.
