Which version of FreeBSD are you running? Are you using 5.X to take full advantage of both processors? To get the 'quantum' upgrade a single faster machine is the way to go. Have you done any profiling to see where the current bottleneck is? Is it I/O, CPU cycles, network? In many cases it would make sense to put in another box to distribute the network/CPU load but that comes with increased storage complexity (getting all machines to write to a common filesystem)... but given that spamassassin and clamav are CPU and memory intensive I'd think that was a solid tradeoff. For the cost of buying one BIG machine you could get 2-3 of the size you have now and distribute the load.
