MSI Computer GeForce GTX 1070 AERO OC Graphics Card currently $419 USD on amazon.
I was able to get $5 off using a friends invite code to drop it down to $414 USD and then added a pickup location at one of amazons drop off points in my suburb to avoid the delivery fee. This might be a Prime only offer? not to sure. You can use the free 30 day Prime trail either way. Just make sure you cancel it, which i did the day after activating it. You'll need to redeem the code from the mobile app. Once youve done that its in your account ready to use.
If you want a 1070 with a better cooler check out the MSI GTX 1070 ARMOR 8G OC - $429 USD on same page
