Great, thanks! I suppose that single AMD 64-boxes will have a similar
advantage over 32-bit Pentiums?
We're currently looking into obtaining a dual CPU box - using the
NUMA-architecture instead of plain SMP sounds like it's definitely the
way to go, right? I've read a couple of head-to-head tests between dual
Opteron and dual Xeon Nocona (EMT64) systems, and both CPUs seem to have
an upper hand in differnt areas. We don't care about rendering speeds in
Lightwave or compilation times with GCC - what we're interested in is a
good CPU for BF2. Is there, to your knowledge, any noticeable difference
between a dual Xeon Nocona and a dual Opteron system wrt. BF2? A
dual-Core CPU would also be highly interesting, but I suppose there is
very little you can say about systems based on this new architecture?
