I wish DDR3 dropped at fast as DDR2. I remembered when I got my first 2GB kit, it was $60 after rebate and even that was a deal since most 2GB kits were $100 - $110+. Especially mine since they're CL4.
We'll be seeing more and more DDR3 drop as time flys by. Hopefully they get more and more affordable and faster.
For my next rig that I'm building within a couple weeks, I'll be Dropping in a 4GB (2X 2GB Set) OCZ CL4 for the price of $80-$90.
Parts Still Missing:
Gigabyte or ASUS P45 Motherboard
OCZ or Corsair 2x 1GB DDR2 800
Seagate 7200.11 32Mb Cache 500GB Hard Drive
