1366 Overclocking advice

Howdy everyone, I wanted to ask the best around considering I'm doing my first full Solo MB/computer build tomorrow, kind of a final exam so to speak.

I was going to keep my i7 920 and overclock it, good enough till fall when I will be building another PC around the 3930. I'll give this to a friend as a gift. I also have a chance to pick up another i7 1366, either a 930, 950 or 960 very cheap and slap it into an ASUS Sabertooth x58 I grabbed cheap as well.

Here's my question;
I hear the 920 is awesome OC'ed...but what about the 930, 950 and 960?
Since I need one more CPU and plan to OC that as well, which one should I grab (Price isn't an issue)?

ASUS Sabertooth x58
16 gigs Vengeance DDR3 1600
GeForce 560 ti Twin Frozer x2
Cougar CMX1000
Coolmaster Hyper 212 EVO

Thanks !!!!

I did a search and found pretty much what I needed to know..I suppose the 960 wins...Thanks anyway..any final thoughts would be appreciated
