Bad wording, I'm still sticking to AMD. Haha.
But it's tempting to switch to the Dark Side. :P

It will be interesting to see how nVidia positions the Geforce 1060 though, if they get the price/performance right, then Polaris is going to be struggling up stream without a paddle.

Needs a back plate, otherwise the PCB warps over time. - I intend this next upgrade to be my last one for a few years.
Having a dual-Bios would be a bonus too, with a switch.

GTX 980 performance with 6GB (192-bit) at $250 and using 120W, if rumors are true.

That's clearly a work-in-progress board .

And you won't get "a few years" from a x80 AMD card, although that depends on how many are a few. As you say, you'll have to wait for 490/Vega.

I gathered that from the Testbed.

And by a few years I mean 2-3+.
It's Vega or it's nothing at the moment.

I want to get one of these cards, but I hear the power draw in them is high. If that's the case, I might need a new mobo as this one is pretty old. But If I do that, I may as well upgrade my CPU, Only got enough on hand to get one right now. This GPU, or a CPU + mobo combo. What to dooo?

What's your hardware first? You might not need a CPU or Motherboard upgrade.

Wait for the Custom Cooled editions.

They will have 8pin power connections on the board, or double 6 pins, and better cooling.

AMD has released a statement about it's Polaris cards using more power than they are meant to.

http://www.anandtech.com/show/10465/amd-releases-statement-on-radeon-rx-480-power-consumption

"As you know, we continuously tune our GPUs in order to maximize their performance within their given power envelopes and the speed of the memory interface, which in this case is an unprecedented 8Gbps for GDDR5. Recently, we identified select scenarios where the tuning of some RX 480 boards was not optimal. Fortunately, we can adjust the GPU's tuning via software in order to resolve this issue. We are already testing a driver that implements a fix, and we will provide an update to the community on our progress on Tuesday (July 5, 2016)."

In other words, they will fix it with a driver update. There will likely be BIOS updates as well for some cards.

Neither, wait for 1060 launch...if those leaks are true it will beat RX 480 in both performance and TDP for similar price.
