One reason you may be loading maps faster than your peers, may be because you have a faster LAN adapter and/or internet connection. That's usually why some are ready before others.
The loading I was referring to is much more dependent on CPU cycles than on my connection speed which actually is not the greatest to speak of. I was able to test this because I just moved also... going from 12-15mb connection to a more relaxed approx. 8 mb connection =/
More than half of my peers have faster connections than I do, now. The example I am using, by the way, is League of Legends and I am not saying you are wrong, but CPU cycles have the most effect in this example by my testing. My setup is not much different than the original posters. I am using a 1st gen Core i7 2.6GHz CPU @ 3.8GHz with 6GB of Corsair Dominator Tri-channel series DDR3 and a single GTX 560 ti on an Asus P6T. I remember testing it using assorted benchmarking wares, post build, and not being much impressed by what I was seeing either, results wise.
Back on topic.... As with any i7 OC, did you make sure to turn off the "speed boost" stuff in the BIOS? Some BIOS call it by different names, but you don't want your CPU flexing more cycles out of an already OC'd setting. You may just be getting throttled for it being enabled.
