We use XEON Quads (PowerEdge 6650s) and they work nice, provided you configure the 
postgres properly. Dell is the cheapest quad you can buy i think. You shouldn't be 
paying 30K unless you are getting high CPU-cache on each processor and tons of memory.
I am actually curious, have you researched/attempted any postgresql clustering 
solutions? I agree, you can't just keep buying bigger machines.
They have 5 internal drives (4 in RAID 10, 1 spare) on U320, 128MB cache on the PERC 
controller, 8GB RAM.

        Subject: [PERFORM] Quad processor options

        I am curious if there are any real life production quad processor setups
        running postgresql out there. Since postgresql lacks a proper
        replication/cluster solution, we have to buy a bigger machine.
        Right now we are running on a dual 2.4 Xeon, 3 GB Ram and U160 SCSI
        hardware-raid 10.
        Has anyone experiences with quad Xeon or quad Opteron setups? I am
        looking at the appropriate boards from Tyan, which would be the only
        option for us to buy such a beast. The 30k+ setups from Dell etc. don't
        fit our budget.
        I am thinking of the following:
        Quad processor (xeon or opteron)
        5 x SCSI 15K RPM for Raid 10 + spare drive
        2 x IDE for system
        ICP-Vortex battery backed U320 Hardware Raid
        4-8 GB Ram
        Would be nice to hear from you.
