Wow this is confusing...
Overclocking means you are running your components at speeds greater than their defaults. If you get an i7 CPU, you'll honestly never need to OC it. It just isn't ever going to be a bottleneck for your system. That said, you do need specific parts in order to be able to overclock (unlocked CPU, motherboard starting with a Z).
So if i buy an i7, i wont have to overclock my computer for say the next 2-3 years? That being said i will probably still buy overclocking parts (if the extra cost associated with it is not high). I found several i7 cpu's on umart.com;
Intel Core i7 4770K LGA1150 CPU 3.5Ghz 8Mb Cache Haswell ($429)
Intel Core i7 3770K/3.50GHz/8MB CACHE/LGA1155 Ivy Bridge ($380)
Intel CORE i7 4820K/3.70GHz/10MB CACHE/LGA2011/4CORES/NO FAN ($365)
Whats the difference between all these i7 cpus? What would you recommend?
The case you have selected will be fine for either of those power supplies. The Antec power supply is a good one. My suggestion for a 550w or greater came when I thought it was necessary for you to get a 780 GTX (I no longer think that since you'll be at 1080P). Corsair is a very solid brand with very competitive pricing. The 520 Antec still might be okay for a 770 or 280x, but I would just get a 550w to be sure.
I think i might as well go with the corsair 550W, because if it provides slightly more power and costs $13 less than the antec, then i suppose its a better choice.

As mentioned above, a GTX 780 will be overkill if you are gaming at 1080P. If you want 100+ FPS now and into the future, go for it, but a GTX 770 or 280X would be more than adequate for 1080P (you'd be looking at 70 FPS average in maxed out new games).
This is interesting - if i choose the 770, then i get a price reduction of $200 which is massive. But if i get the GTX 770, will it still easily support good performance for future games? If i go the route of 770, then would it even make sense to get an i7 cpu with it? There are 2 different Gtx 770's on umart, is there even a significant difference between them? Whats recommended by you?

You should pick up an i5 4670K, an ASUS Z87-A motherboard and (at least) a coolermaster Hyper 212 cpu cooler. Overclocking is fun and easy to do. And you get free extra performance. Who doesn't want that?
It won't significantly shorten the life of the cpu (perhaps from 30 years down to 15. At any rate, you'll have tossed the PC in the trash long before the CPU wears out)
That motherboard is pretty expensive ($199) - what advantages does it have other than overclocking? Also if i choose to overclock, is the cpu cooler a must have?
So i guess based on suggestions here is the modified build
