I guess another concern I have is whether or not the 970 will end up being stuck in middle so to speak. I had this problem with 2 previous cards in which they ended up being both too fast (pointlessly faster than the slower options I was considering. basically locked at 60fps even with low utilization) while also not being fast enough for other usages.
Yeah. This is why you shouldnt even consider a 980, they are exactly like this. Not enough faster to be worth the money in the long run. The 290/390/970 are all about 50% faster than the 960/285/380. 50% is noticeable even longer term.
Between the 290, 390 and 970 just get whatever has a better deal including game bundles and quality of cooler on the aftermarket models available. They're all close enough as to be interchangeable for 1080p.
