Sold my first OEM X3350 for $400. Picked up a Retail version for $339.
This one Core 2 runs 16C hotter than the coolest core. Whereas the first OEM only had an 8C Spread over the 4 cores. Howver this run ones at 3.840 (480x8) with less VCore and FSB Vtt.

Tried this X3350 in a Maximus, a Rampage and a P5E3 Premium. Core 2 runs a lot hotter than the others. But it out performs the first X3350 which ran cooler. OH Well, the retail version has a 3 year warranty.

Here are my 3D Screen shots and ORB Link.
