Has anyone considered Opterons? Our preliminary investigations indicate that the Opterons have a considerably better bang/buck ratio then anything else out there right now, particularly Xeon, even in 32 bit configuration. We're getting dual processor Opterons in the under $3k price range. I'm anxious to try out my first G5 cluster one day, hopefully soon, but the Opteron path makes more applications available to me.
