Obviously you'll have to wait for the GTX 1070 to become available at this price, which would be around late June, but here you go.

Get the CPU and motherboard at Microcenter for the bundle discount. I included the discount towards the motherboard pricing.
I have no idea what aesthetics you'd prefer for the case, so I guessed. It's a good case though.
Things to possibly change:
Instead of getting the 850 EVO SSD, you can get the PNY CS1311 for $26 less and not lose much performance.
Go for the 1TB Seagate ST1000DM003 HDD and save $20 there.
Either of those choices would allow you to get the i5-6600K CPU instead, which has a decent bump up in clock speed.
