welcome to the forums jeff. I'm glad to see more ppl undertaking the joy of building their own pc. PC gaming is way better than console by a long shot. since you are a newb, i will explain everything in detail to help you out.....( as i once was a newb my-self). my aim is not to insult your intelligence but to help. now picking parts can sometimes be overwhelming ex. z97, h81,z87,x79,x99. these are just a few types of motherboard chipsets. (Chipsets are another chip made by intel to put on a motherboard to control other functions like USB, SATA ect.) you will want to stick to Z97, well because its the latest chipset.
So Here we go
CASEThis is my favorite part of PC building, it is the part you will look at the most...lol
you will want a case that is ATX/E-ATX compatible. most cases will have this. (ATX/E-ATX is and industry standard for motherboard layouts) The hero you were looking at is an ATX....
You will prolly want to spend $80-$150 on your case, also stick to brands like Corsair, coolermaster, NZXT. here are some recommendations on some.

When choosing a PSU there is more than just Wattage. look at the specs on the side panel of the PSU and look for the box that says 12v and under it will be an amperage. the 12v rail is what feeds your Graphix card. your 770 needs more than 20amps of juice. the evga 750G is a good psu but it is made for the 720,740. you will want the evga "G2" line of psu.
its silly not to get a gold rated psu because they are cheap now compaired to what they used to be. also with this stick with EVGA, Corsair, sea sonic. i recommend a 850w psu. that is more than you need at the moment, but you will want to add a second card, you will want to start overclocking, you will want to add better cooling to your case. this is just how it is you get the bug to build a pc and it never stops there. you will want to spend $125-$175 on a psu.

Nehalem, westmare, sandy bridge, ivy bridge, haswell. yet to come are broadwell and skylake. the great thing about getting a Z97 mobo is it will work with broadwell cpus at the end of next year( with a bios update of course). the ones you will want to look at really are the I5 4690k and the I7 4790k. now if you see a 'K" tacked on the the end of an intel cpu it means you can overclock it. if ther is no 'K" it means that it is harder to overclock. there is also these same cpus with an "s" on the end, dont worry about these, they use less power thats all.
the main difference between the 4690k/4690 and the 4790k/4790 is hyperthreading. this is good if you convert a lot of video files, or if you like to edit video or photos.( there are some instruction sets that the i5 has the the i7 dosent but this will have no effect on you.) by the way the i5 4690/k is more than enough for gaming. the frames per second difference between the 2 is about 1%. now if these are to expansive there are others to choose from. just let us know. but both of these will give you a solid platform for many years.

Happy building.
