It should be noted that according to most benchmarks I've seen, the amd64 chips are the fastest 32-bit chips available. So, even if you're not using the full 64-bit capability in your apps (or even just running them purely in 32-bit mode), you're in the green. There are other advantage to them (like register space) than simply the 32/64 split. And don't forget bragging rights! Servers always run faster when they're cool... -- Matthew Fuller (MF4839) | fullermd@over-yonder.net Systems/Network Administrator | http://www.over-yonder.net/~fullermd/ On the Internet, nobody can hear you scream.
