PC build advice - GTX 970 SLI vs GTX 980 for the long run?

[[TC] Stephen]

I would always go for single gpu options unless it doesn't provide adequate fps. Multi gpu can be a menace on some games and fine on others. I remember when I had gtx 470 in sli, had to keep turning sli off for just 1 game which got annoying. See how you go with a 980 to start with and if it struggles later on then get another 980, that's what I would do.

And I wouldn't use red drives for storage if you need speed. They are good at running for long periods, but the speeds I get from my nas are at best, 60mb/s. I have a wd black 2tb in my pc and I can get up to 110mb/s, which is great for load times.
