GTX 970 or 980? An upgrade from the R9 280x!

BEFORE YOU READ THIS: I live in Canada so everything is almost double the price here. This means I don't have money to throw around.

All right folks so here's my dilemma: I want to upgrade from my R9 280x for the following reasons:
- I want to try an Nvidia GPU, since the build I am upgrading from is my very first build - 100% AMD
- I want higher framerates: the card is pretty good, and it can run games on high at nice(60) FPS, but not ultra most of the time(fallout 4 is a consistent 30-50 fps on ultra, Witcher 3 isn't playable on ultra at all, 40s for high settings, sometimes 60).
- I have been experiencing a lot of graphical glitches with this card(screen tearing, frame skipping, green screens, my computer sometimes freezes and it will say the graphics card crashed or something)
- It can't overclock very much without becoming unstable

So, I was thinking I might buy the GTX 970 or GTX 980, but I am unsure of which. The 980 is more future proof and runs better, but it costs a lot more. I am also worried that the 980 may no be compatible with my build:

My price range maxes out at about 500 dollars.

It currently takes 500 watts and it is a 750 watt psu. I am also worried if it will fit on the mother board I have. Any and all answers are appreciated.

P.S
Should I be upgrading some of my other components first?

I would say the GTX 970 from a standpoint of it is comparable to the GTX 780 and that card was the uppermost limit of the fx 83XX series. If someone has experience otherwise please step forward as I left AMD after the Pheneom II days. (They are not bad considering prices in Canada)

You should be able to get a GTX 980 in there no problem, remember you won't have the 250W Radeon 280x in there at the same time. Nvidia claims the 980 has a 165TDP, which is substantially lower.

But saying that, I'm not sure it's your GPU limiting you, at least in Fallout 4. I have experience running Fallout 4 on a variety of hardware and it's normally CPU limited and it highly prefers Intel processors.

Any GPU will be compatible (now physically is another matter, but you didn't list a case)

GTX970 and GTX980 use a lot less power then an R9-280X so you are again fine.

I think you would be a bit disappointed with a GTX970, it is not a huge jump in performance, but a decent drop in wattage. GTX980 would be better, but isn't the most cost effective GPU in that price range. If that is what you can afford and you want to switch to Nvidia, it should get you close to that 60FPS goal (maybe not on W3 though, pretty intensive game that)

GTX980Ti would be the ideal single GPU from Nvidia. R9-390X is also not a bad choice. I would probably avoid the Fury at their current prices.

Looking at Newegg,ca, the GTX 980 is priced at an average of $750 Canadian dollars... Price-to-performance wise at 1080p, the GTX 970 is the clear winner between the two.

However, as texture/graphics settings are increased, even at 1080p, the GTX 970 can and will be challenged due to the way the VRAM on that GPU is partitioned. I know first-hand, as I was running two MSI GTX 970's in SLI. Lots of GPU horsepower, even in a single GPU, but is limited by that VRAM issue, which is dependent solely upon your graphics settings.

If you're paying in USD for a GTX 980, for less than $200 more, you can grab a GTX 980 Ti, which is a much better buy/investment than either GPU you are looking at.

Just means budgeting in the mean time until you can pull the trigger to purchase and by then, the prices of the 980 Ti's may drop even more.
