Don't do anything without pictures of the card. Generally speaking, I think $200 for the 1070 is a pretty damn solid price, but if it's a filthy, damaged card or a fake and you don't know until you get there to pick it up, that's a massive waste of your time.

I'd go with this^, much better bang for the buck than if you were strictly limited at AUD$600.00

I'd change it to this:

Default is Auto which usually uses much more voltage than necessary and causes high temps. 
Try setting it manually instead. You should be able to hit 4.2ghz with 1.2v fairly easily. Try that and stress testing for temps. Depending on results, you can tweak for higher clocks or lower voltage from there. 

A used RX 580

LGA 1151 is Skylake...

RX560 Vs Vega 11 not a chance and the other way around, if its a used RX570/470 for that I would take the RX570/470. The difference between RX560 and 570 is like day and night, with your aim of 60fps 1080 the rx570/470 will deliver what you want most of the time with combination of high and medium. 
It's not like I'm super busy at 10am.

Bro ignore people telling you to just "get a new pc" its not always that easy guys, I used to have a i5 2500, it'll make you happy! Much better than the i3 you have,
https://cpu.userbenchmark.com/Compare/Intel-Core-i5-2500-vs-Intel-Core-i3-2100/m517vsm41
to show how much better, and I upgraded from a i3 3225 which is around the same as your i3, to a 2500, and it was sooooo much better in games!

I would wait. AMD will be launching new RX 5000 series GPUs on July 7th. 

I would go with a rx 580, as 590 isn't much better, and 1660 ti isn't worth it for the price (if you ask me) and your psu should be fine!

I extremely highly doubt that is the case here. Far more likely OP's being held back by the CPU+RAM.

I want to second this.  unless the psu in question is absolute crap and i mean absolute crap then it should be fine for a 2400g and a 1060 6gb as peak power-draw for both of these is sub 250 watts underload. Likely a cpu bottle neck in my opinion, id recommend OP actually increases their graphics settings as unless they are using a high refresh rate panel they wont be able to see those extra 30 frames anyways so you might as well get some better looking graphics

It depends if you're gettin the top end one that's about $310 or not; if so, then just pay $40ish more and get a RTX 2060, which's roughly a GTX 1070 TI in performance.
 
Otherwise, it's a nice card for low-low/mid level gamin in 1080p.

ya the 1600 is relatively garbage right now unless u can get it for like....75dollars, at least get a 2600 if u cant wait the 2 weeks.

I am quiet interested why you have chosen this graphics card

For watching movies, videos etc it's fine.  For gaming, especially with your monitor and CPU the graphics card is a rather large bottleneck, yes.

Rx 580, Rx 480, GTX 1070ti, GTX 1060, and others.

get a used Vega 56

I’d keep an eye out for good deals on 3770s
 
the 
motherboards of 3rd gen Intel seem to by dying off regularly around this age and so there will be a few people selling their 3770 chips on when their mobo dies.
 
if you can do the upgrade for cheap then by all means do it, but if you’re paying strong money you’re probably better off selling what you have now and buying a Newer platform.
 
 

3770k is $100-$200 on ebay.  Sell your I5 and you could upgrade for under $100 total. 
 
That would be worth it.

Try and find a used i7 2600K or i7 3770K. 

or evga on sale, brand new with a 1 year warranty

gtx 1070 hands down low $200's on ebay

I'd get a GTX 1650 instead; best GPU for 75W

A rx460 will consume up to around 100 watts, depending on model, amount of video card ram and other things. In the worst case scenario. you can use Wattman to reduce frequencies a bit and make the card use less power, saving 10-20 watts.
 
Your i5 3470 along with everything else doesn't consume more than 100w, so you should be within that 240w the power supply can provide..
