is it worth getting the i5 for the price instead?

The 4670k is by a good deal a stronger processor than the 8350. However, you probably won't notice the difference with just a single 280x. Also, I just picked up a pair of 290Xs for 425 a piece, open box @ the egg. Gigabyte Windforce. So if you shop around on your graphics, I think you can do better for that price.

I would recommend the core i5. Better performance in games, lower power usage (which means less heat).

Both of the processors have dual memory controllers. You should by a memory kit with two dimms (2 x 4GB for 8GB total or 2 x 8GB for 16GB totral).

8GB is enough for now, but 16GB may be required before too long and it's easier to buy the RAM now rather than worrying about RAM compatibility later.

Very good quality power supply.
750W is overkill for a single card build, and not enough for SLI.
Consider the 650W version of the same supply.

R9 280X will be fine for 1920x1080.
If looking at 2560x1440, consider the R9 290.

The i5 is stronger in single threaded applications, not in multithreaded ones.

It is a lot more than this. Any application making significant use of up to 4 cores will run better on the Core i5.
While games are not single threaded, the Core i5 always comes out ahead.
The FX-8350 can only out-perform the Core i5 where more then 4 cores are heavily utilized. Synthetic benchmarks can do this easily, but not many programs can make effective use of this.

Yeah, I just tried to but it simply, I should have said: "not in heavily multithreaded ones."

Thanks for the reply. I forgot to mention that everything here is NZD. The r9 290x is pretty expensive in new zealand about 600 to 800. Is it worth it to downgrade to the amd and use the money i save from that to get a better gpu? my budget is quite tight and every in new zealand is quite expensive :/ Thanks

R9 290 and 290X are not the same. The R9 290 is much better value.
Unless planning for 2560x1440 resolution, just stick with the R9 280X or GTX 770.

You are able to keep you CPU longer than your GPU. Don't downgrade this unnecessarily. You will find in two years time that the GPU you buy today is much slower than new offerings, but processors won't have changed to the same extent. This makes a future graphics card upgrade while keeping your other components reasonable.

You could get the next psu which will do fine too,it just isn't gold rated,From a review at Techpowerup i saw that it doesn't do well on low loads=<80watts for efficience,maybe/probably it's week point.
http://nz.pcpartpicker.com/part/antec-power-supply-hcg750m
and i do think that crossfire will be possible on 750watts.

For that review,

Antec HCG series are manufactured by Seasonic. Good quality, but as you said 80 plus bronze rated rather than 80 plus gold.
The HCG-620 or HCG-620M would be sufficient for this system.

Core i5 4670K TDP is 84W
R9 280X, 290 and 290X and GTX 780 are all rated at maximum 250W.
GTX 770 is rated at 230W.
2 x 250W = 500W
Allow 40W for other components.
Total maximum usage is 624W.
Most of this is on the +12V rail, allow maximum of 80% of power supply rated capacity.
Power supply chosen should have a minimum of 65A on the +12V rail (compared to 39A with only one card).

Some suitable supplies for this system with two cards:
Seasonic X 850
Antec HCG 900
Corsair TX 850
Corsair HX 850

You are paying quite a premium for these models over the 600W to 650W versions suitable for a single card system.
