I hate to break it to you but with the higher fsb on the E6750 you have less overclocking headroom. For a E6750 to reach 3.6GHz you need a 1800FSB and 900Mhz ram. For a E6600 to reach 3.6Ghz you need a 1600FSB and 800Mhz ram. If you have the cooling the higher multi on the E6600 will pay off since its clock multi is higher. Thats why its more money.
Overall a E6600 is a E6750 I say this because if I drop my E6600 multi to 8x and set my fsb at 1333 I get 2.66Ghz the same as a E6750. You can check out a full thread I wrote up a bit ago on my theory that they are basically the same chip besides the stepping. You should find quite a few interesting replys on the topic.
