I'm wanting to know if you guys think I should do a GPU or CPU upgrade first. I'm using an FX8350 over clocked to 4.3GHz on an Asus Sabertooth 990FX with an MSI GTX760. I'm staying at 1080p for a while and this card gives me a constant 60FPS or more at high settings on BF1. If I did my GPU, it would be a 1060 or RX480. If I did my CPU, it'd be either an i7 5820K or 6800K. I might even do a Skylake cpu. However, I wanted to get the X99 Micro from evga. Thanks! I'm happy with the GPU so far, but I figured a cpu upgrade would allow me to edit and render videos faster.

GPU 100%

Go for a GTX1070 or pick up a used GTX980Ti for around 300$ with some warranty left one it.
GTX970 I have seen used for 140$ with 2 years warranty left on them.
EVGA cards of course use the guest RMA,
 

I'd go with CPU. With Kaby Lake now shipping, prices are about to drop on Haswell-E, Broadwell-E as well as Skylake.
 
A while longer and Nvidia cards will too, with the anticipated launch of AMD's Vega and subsequent Nvidia Ti's. Existing 1080's will be a bargain.
