Stable like a rock.

The Athlon itself is "SMP-ready", but there are no SMP main-
boards yet. They have been announced for Q1/Q2 2000.
But you probably don't need SMP anyway (and there are only very
few applications that really benefit from SMP). A UP Athlon on
on its own is already an exceptionally well performer, thanks
to its large caches and well-designed processor architecture.
I also have a dual Celeron-466 box, and I don't like it as much
as the Athlon. The Celeron's small memory caches and low bus
bandwidth waste a lot of the performance. It's a nice toy if
you just want to play with SMP, but Celerons don't really make
sense in a serious SMP environment.
Just my 0.02 Euro.

Oliver
