Depending on how much "cpu intensive" work you do and youd budget, Opteron or Power. I've seen some benchmarks between the Intel EM64T and the AMD-64. For CPU intensive work, they are roughly equal, but for memory or peripheral issues, AMD-64 is better.
If you ise AMD-64 or compatible, also look at Interl's icc: it can save a truckload of CPU. Intel's ICC compiler can generate some very efficient code. I did some benchmarks on the IA64 with the ICC compiler against GCC, and found results were significantly faster using ICC. GCC is certainly better for portability, but ICC has a mode for full GCC compatibility. It is a closed source compiler, but is free for personal use.
Also note that a 64-bit application may not run faster in 64-bit mode.
Depends on the application. When building on x86-64 platforms, you can
chose to build either 64-bit or 32-bit.
