Is there a current opinion on this? I heard that costs have come down to 'close to dual xeon' prices, but is it safe to run -STABLE on it? Other then memory allocation above 4g, are we seeing any benefits right now with running this? Or are we dealin with 'running 32 bit apps on a 64 bit arch' still?

If you want to run -STABLE on Opterons right now it would have to run in 32-bit mode, and thus not be much different from running on Xeons. -- <Insert your favourite quote here.> Erik Trulsson ertr1013@student.uu.se

FreeBSD/i386 is 32 bit, and FreeBSD/amd64 is 64. And FreeBSD/amd64 is only available for some current snapshots right now, not 4.x-stable. The prices for Opterons should be considerable less than Xeon's especially for single CPU systems. Opteron 100s are the same thing as the AMD 64 FX chip (same socket too). And nVnidia NForce Pro boards are fairly cheap. Beware that the AMD 64 (non FX version) is not an Opteron chip, and has a different socket. Nearly anyone can get an inexpensive high-perf 64bit system now. Tom
