I'm planing on buying an R9 390 to upgrade from my 670, but with AMD having just revealed their new Polaris architecture that basically doubles performance per watt, would it be a good idea to wait for that? It'd certainly be a big boon compared to how much power the 390 eats, but would there be a high-end card available early on in the releases or would it be later in the year?

Not sure how connected CES is with video cards but a lot of other information comes out that might reveal what you need video card wise.
Please do not respond to me, even if I ask you a question, its rhetorical.

There's also a question of double performance per watt as compared to what? Going from 28 nm to 14/16 nm, you'd expect nearly double energy efficiency from the process node alone. Doubling Fiji efficiency would be much more impressive than doubling Tahiti efficiency, though. Indeed, Fiji isn't really that far shy of doubling Tahiti's efficiency, especially if you're willing to count the R9 Nano.
A lot depends on how long you're willing to wait. If your GTX 670 is on its last legs, you want something new now. If the GTX 670 is still working fine and you're in no rush, I'd wait until you do have some reason why you need to upgrade. Sometimes that takes a few years longer than you expect and maybe you end up finally buying a Radeon R9 600 series or GeForce 3000 series (I have no idea what comes after the 900 series) card on a 10 nm process node.
AMD announced Polaris today, but Nvidia Pascal is also due sometime in 2016.
Basically, you might have a better GPU in six months of waiting, but it may be a buggy, unoptimized, crashing monstrosity for all we know right now.
When new stuff is out, you can look at the tests and make informed decision, you can still end up with 390 ;P
OTOH, it never hurts to look for great deals for upgrade. 390 is great GPU, and FX 8300 is so cheap that its a no brainer and great mid step until you wait for new cpus as your CPU will be bottleneck in most games, so buying just GPU will be pointless.
You can look at this video (most interesting 3:25 onward) to see how dual cores perform (very) badly G3258 OCed to 4,5 GHz and i3.
Had a GTX570 in it but having (finaly) loads of problems with 1440p content with just 1.2Gm mem
Was thinking about a gtx970 but i ended up with a verry CHEAP GTX780ti verry happy wih it.
Other pc has a 4970k and a R9 290x.
Hovered over the Fury X Fury Nano "buy" button alot but decided to wait until the HBM version 2
And see what nvidia come up with
Historically, AMD has beaten Nvidia to every single new process node for discrete GPUs since buying ATI. This time, there's no guarantee that they'll use the same process node, which could shake things up. AMD has officially announced that they're fabricating something or other at Global Foundries and apparently says they're fabricating something else at TSMC, and is rumored to also be using Samsung. If AMD and Nvidia aren't using the same foundries for their first GPUs, that could shake up the order if one foundry's process node is delayed far more than another's.
In your current system, I'd see the CPU as a much bigger problem than the GPU. You could get a faster CPU and drop it in your current rig. Sandy Bridge and Ivy Bridge are discontinued, but if you could find a used Core i5-3570, that's a nice upgrade. Though it sounds like you may want an additional computer while leaving the old one functional.

"First and foremost, Polaris will encompass both GDDR5 and High Bandwidth Memory (HBM) products. Where the line will be drawn has not been disclosed, but keeping in mind that HBM is still a newer technology, it’s reasonable to expect that we’ll only see HBM on higher-end parts. Meanwhile the rest of the Polaris lineup will continue to use GDDR5, something that is not surprising given the lesser bandwidth needs of lower-end parts and the greater cost sensitivity.
"Meanwhile RTG has also disclosed that the first Polaris parts are GDDR5 based. Going hand-in-hand with what I mentioned earlier about RTG’s Polaris demonstration, it seems likely that this means we’ll see the lower-end Polaris parts first, with high-end parts to follow."
There's no guarantee that the first Polaris part will be faster than the R9 390 that you're looking at or even the GTX 670 you already have. Nor, for that matter, that the first Pascal part will be faster. Both vendors traditionally launched the top end card first. With Kepler, Nvidia moved to an upper midrange card first. With Maxwell, Nvidia actually launched the low end card first and worked up from there.
If AMD and Nvidia launch some really nifty $100 or $150 cards in several months, that doesn't necessarily shake up the prices on $300 parts. That could still be a big deal if your main complaint about the GTX 670 is dumping heat into your room, but that doesn't sound like it's the case.
To double your performance, you'd need to look at something more like a GeForce GTX 980 Ti or Radeon R9 Fury. That's a different price range entirely.
Somebody, somewhere has better skills as you have, more experience as you have, is smarter than you, has more friends as you do and can stay online longer. Just pray he's not out to get you.

This chart is somewhat helpful for anyone considering it: http://www.tomshardware.com/reviews/gpu-hierarchy,4388.html Not perfect but gives people the general idea at least.
I say just get something. I had planned on having a new rig last summer, but now it looks like i"ll be waiting till Spring. I'm not asking anyone again since i dont' want to be convinced to wait until Summer again for the new hardware lol.
My 2 cents
