The 670 has a higher clock rate and the turbo boost really moves you up. I only see lower cache which is typical of the hyperthreaded designs as you really get 2MB/core. The 670 wasn't available when I bought my 661 or likely I would have gotten that one. The 661 price at NewEgg is about the same as the 750. The 670 is, unfortunately, $100 more. (Sorry!) ;-) i5-750 =3D $195 i5-670 =3D $299 i5-661 =3D $209 Have fun and don't using Intel stock cooling! :-) - Mark -- To unsubscribe from this list: send the line "unsubscribe linux-rt-user= s" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
