I will warn you that the AMD brigade will try their best to sell you the 480 but you seem smart enough to see the numbers for yourself.
I have HD7970, various RX 480s, R9 390, R9 295X2 and
3x GTX 1070s. GTX1070 is
not worth $380 compared to a $180 RX 480 4GB for 1080p gaming no matter how much you spin it. The only reason 1070 even looks good right now is because of how awfully overpriced 1080 and Titan XP are and due to lack of competition from AMD. Otherwise, the GTX1070 should have been $329 MSRP like the 970 and that in itself was overpriced considering GTX970 is just a $199 GTX560's successor. NV literally doubled the price of GP104 x60 card and rebadged/marketed it as a fake x70 card. GTX1070 is only 45-50% faster than an AIB RX 480 despite more than double the price. It's especially not worth the $ when paired with a stock i5 since those high FPS that professional reviews with 4.5Ghz Skylake CPUs show are not going to be what the gamer experiences with a 3.3Ghz i5.
Remember don't buy a 4GB card no matter what anyone says because you WILL regret it. Good luck and happy gaming.
There is nothing wrong with buying a stop-gap GTX1060/RX 480 card for 1080p gaming. Since 144Hz gaming cannot be achieved with a stock i5 6500, what exactly is the point of spending $380 on a GPU whose performance will never be realized? By the time the OP upgrades to an i7 processor in 2 years, there will be a card 40-60% faster than GTX1070 for $400.
Some of the 1080p144hz TNs are not as bad as you'd think. Specifically the Nixeus VUE24 is quite nice and reasonably priced
In my opinion, many gamers who have used 27-35" VA/IPS gaming monitors would never go back to game on a tiny 24" TN panel. What's the point of fast refresh rates when all the colours, blacks and whites are all of poor quality and you have to suffer gaming on such a tiny screen? A high quality larger screen monitor benefits in media, games, productivity, web browsing consumption, etc. A low quality small screen size high refresh rate small screen size TN panel has limited appeal as it's not a well-rounded choice outside of fast FPS gaming.

Going with this ^ monitor and if budget doesn't allow downgrading for 2 years to a GTX1060/RX 480 over GTX1070 is preferably imho than buying a 1080P 24" TN 144Hz panel with a GTX1070. In 2 years, the GTX1070 is outdated, but that 27" 1440p 144Hz IPS monitor is still going to be good.
