Starting at the processor I suggest a LGA-2011 socket i7-4820K with 3.7 Ghz stock speed 3.9 Ghz turbo
I am going to suggest going with an excellent mother board for the money The Gigabyte GA-X79-UD3
It has a lot of features found on many high end boards without the price , Solid as a brick and reliable as the you're going to get.
I suggest liquid cooling
I suggest a 700 watt power supply
I suggest a GFX card by NVIDIA say a GTX 660 Ti or above
I suggest high speed DDR3 RAM chips no less than 4 gig
I also suggest a SSD and a 7200 RPM Hard drive with no less than 1 Terabyte of capacity
I have the i7 4770 on a different computer with a better Mobo and the 4820-K smokes it so that is the only reason I do suggest the 4820-K also it is a little cheaper and has a higher stock clock speed than the 4770-K The 4770-K is a beast don't get me wrong but why would you spend more money for less performance just because it is a newer chip?
Oh, the 4770-K is a completely different LGA-Socket so the 4770 will not fit in the 4820-K's socket is the 1150 , Good luck to you and I hope you build something nice for not too much money , for me it has always been about Maximum power for not maximum money and I believe with the list I provided, that is am extremely capable machine to get you well into the future .
