Should be fine, though I've only personally used systems with 16G, I've had individual processes approach 30GB using swap (though not on purpose, *cough*). > Are there any other things to be noted? like.. some popular hardware > not working with > 4GB memory and such.

I bought an LSI MegaRAID (amr(4)) for the bulk of my storage. http://lists.freebsd.org/pipermail/freebsd-amd64/2006-March/007827.html No problems with if_bge/em, USB, etc. Here's a more useful list of drivers: http://lists.freebsd.org/pipermail/freebsd-amd64/2006-March/007758.html -- Thomas 'Freaky' Hurst http://hur.st/
