q6600 dropped to $275 @ www.mwave.com today.  I ordered mine up... I have the case built up on a GA-DS3-DSP / 8800GTS 640MD / 2 GB A-Data Extreme DDR2 800 and a 1TB raid 0.  I should be able to OC to about 3.2 no problem... I will let you know how it compares to my Barton 2800 that I am on currently.  Owwww....
