Want to build my first PC. Need help with parts

I want to build my first pc, but need to sell my gaming laptop first before I will do that. I have an idea on the hardware that I will need, and also have some of the components that I already want.

intel i5 4650k
nvidia gtx 770(maybe 780 if I can enough from selling my comp)
16 gb of ram
motherboard-need help but I would prefer all usb 3.0, don't know whether that is possible and would prefer to have at least one thunderbolt port.
Case-anything that will keep the pc cool and has usb 3.0 that is accessible.
cooling-I dont plan on OC'ing but if the cooler price is worth than I would try to do it
ssd- I have a samsung 840 evo 120 gb right now, so I am cover
optical drive-just something basic no need for bluray

I should have 1300$ for the build, but I want to make sure this will be compatible for g-sync, because I plan on getting a g-sync monitor.

Thanks in advance

I believe G-Sync works with any Kepler GPU so a GTX 770 or 780 should be compatible.

This is a new motherboard from ASUS "Z87 Deluxe Quad". Has 2 Thunderbolt 2 headers on-board.

IDK if there are cheaper boards supporting Thunderbolt 2. Eating up over $300 of your budget just on the mobo when you only have $1300 seems a bit foolish, I must admit.

The CPU you want is the 4670K. The 4650K does not exist.

Get 16GB of 1600 or 1866Mhz 1.5V or lower DDR3

Pick up a reasonably decent CPU cooler so you can do some overclocking. It's not complicated to do these days.

Grab a 1TB WD Blue or Black HDD.

When you select a GPU, go for 3 or 4GB of GDDR5. Don't get a 2GB card. Very soon will come the day when 2GB is insufficient.

and you're set.

What alternatives for a motherboard are there? Would it be worth waiting for the nvidia gtx 8xx series of cards? or just go for this generation. It the price worth the upgrade from a 770 to a 780?

Thanks

Here's a comparison between the 770 and 780. You don't get as much performance per dollar the higher you go. $200-300 is the performance sweetspot for video cards in terms of price/performance ratio

I don't think it's worth waiting for the next generation of cards. Obviously, they will be much better, but they are a long way off at this point.

I can't tell you what alternatives for a motherboard there are because I've never looked into thunderbolt motherboards before. I'm just as much at the mercy of newegg and google searches as you would be.
