With changes that Ps3hacker12 lists you are in good shape on the build. I do see that you are looking to use this as a gaming machine; if that is the case then you might want to think about stepping down to the Intel® Core™ i5-2500K. The reason to step down is that very few games can take advantage of more than 3 threads. Because of this the value of hyper-threading which is the main difference between the Intel Core i7-2600K and then Intel Core i5-2500K has little value in a gaming environment. So it comes down to 100MHz for $100 which isn’t very good value.
Also while the Intel Core i5-2500K and Intel Core i7-2600K do come with HSF (heatsink/fan) that will work fine at stock speeds if you are going to overclock them you are going to want to add a better cooling solution.
