I've been back an forth on whether to go R9 290/X, GTX 970 or even a 2nd hand GTX 980 and while I think I've decided to go down the Nvidia route, I'm not sure which one to go for!?!?! 
I am drawn towards the lower PSU requirements, temperature and noise levels of the Nvida cards but can't decide which 970 would be the best to go for with a circa £290 budget! (even a 2nd hand 980 is another £100 or so and I'm not sure it's worth it, even with the 3.5GB VRAM issues on the 970)
Is there much to choose between the cheapest half a dozen or so 970's?
