I was hoping to pick-up a Revised Quad 3.0 when the Octos were announced, but that was based on the supposition that prices were going to drop for the existing configurations.
With my ADC Hardware discounts about to expire and a $500 gift card that would account for a $1,000 price drop, I bit the bullet on a "lesser" system:
2.66GHz Dual Dual-Core Xenon
250GB (+200GB Seagate 7200.9, +750GB Seagate 7200.10 existing SATA drives)
1GB RAM (+2GB ordered from DMS)
X1900XT
Bluetooth
802.11n
Total out of pocket was $1,913.62 (including $152.62 in taxes)
I figure I'll get at least $1,600 of that back when I put the G5 2.0GHzx2/3.5GB/160GB/BT/802.11g/Radeon 9800 on eBay.
Plus, I have to pay for the CS3 Design upgrade and a Canon EOS-1D3, which Canon is selling for $500 more than the price announced at introduction... (grrrr)
