I have two dual opteron 248's with 4g of ram each, 6x36G 15k rpm ultra 320 scsi disks in hardware raid 5, and they are by far the fastest machines I've user used. As far as this "headache" of using 64 bit Linux, I've experienced no such thing. I'm using gentoo on both machines, which are dedicated for postgres 7.4 and replicated with slony. They're both quite fast and reliable. One machine even runs a secondary instance of pg, pg 8 beta4 in this case, for development, which also runs quite well.
