I would say go with the 146, they are better overclockers than the 148's as I have seen. Even though you would expect it to be the same core, just a lower multi. But it's up to you, determine if it's better for you to have a x11 multi or a x10 multi. If your memory would like a x11 multi for 1:1 performance, get the 3700. If it doesn't matter, then I would get the 146.
