Be careful; check the unlocking guides for palaminos before you decide to try. Also, it's coming up to winter, these chips will nicely warm your whole living room (joke) but they already run warm, I had a heck of a time cooling mine, can't imagine overclocking the thing. They're also the "top" of the palamino line in terms of speed so really don't have much headroom.
So many 1700 tb'b's cry out for new homes at the buy sell trade forums; also nice tbred 2100's - but I know, sometimes we need a challenge.
