Honestly if I were you I would go with a 2500K and just do a moderate overclock. If you plan on going with a multi GPU setup not overclocking your CPU will bottleneck them. Plus the 2500k is only $15 more so its not really wasting any money for a lot more performance.
For a GPU go for a 580 but if that is to much money get two 460's, higher performance for around $400.
For the Mobo get the P8P67 PRO which you can get in a combo deal with the 2500K.
I like the XMS3 set that was posted above, pretty freakin cheap too!
I would go with a 750W PSU, something like the corsair HX750.
Get the spinpoint F3 1TB drive.

So that motherboard should be fine for what he is using it for.
He doesn't need the 2600K as it makes very little to no difference in games, so he can save a fair bit of cash there and get a 2500. He also doesn't need the K edition he stated. 8gb of ram is also cheap, so in my opinion it would be a good investment as games are starting to go 64bit, so you will see more then 4gb being used at one time. (including os and background stuff like antivirus or webbrowser)
580 is a very good GPU but could be a little overkill. Perhaps you could wait and get a 570 to save some $$$.
Now, with all this save cashed your probably wondering what you should do with it. Simple, invest in a SSD. Even with the 580, you might still have enough for one if you get an i5-2500. You will not regret it
Games have been using 64bit engines since vista....They are still not using more then 2GB's of ram at the most.
