I'm in the market to upgrade my gpu to prepare for 1440p at max settings and have been looking at the maxwell series of cards. I have been looking at the 980 but for fun looked at what the estimated wattage would be with sli with two 970's (http://pcpartpicker.com/p/RHkZWZ)
Either option seems viable but I do want the best gaming experience I can, hopefully as close to at least 50-60 fps average as possible. If I get the 980, I plan on overclocking it as much as possible because of all the extra power I have left in my psu. If I get the sli, I have to keep the two cards at stock so I don't go over my power limit

gtx 970 sli on 650w impossible. Buy the gtx 980 single card and in the future sli the 980. How ever even a 980 is a overkill. Since the 970 beats the gtx 780.So in the end I have to upgrade my psu in the long run anyway? I'm not too sure I can even pick up another 980 in the future, although it might just be safer overall to go one card for now.
Would a 980 be good to play 1440p at the settings I want though?
Could just save an extra hundo and update the power supply.
I might do that. I found a 750w version of my powersupply for 109.99. Would the 980 (single) be enough for 1440p?

Forget pcpartpicker for wattage determinations:
1. Look at nVidia website
http://www.geforce.com/hardware/desktop-gpus/geforce-gt...
98 C = Maximum GPU Tempurature (in C)
145 W = Graphics Card Power (W)
500 W = Minimum System Power Requirement (W)
2x 6-pins = Supplementary Power Connectors
So for SLI = 500 watts for system w/ one card + 145 w for the 2nd = 645 watts
With overclocking, figure a 750 watter
2. Do a web search on "Guru3D [ card name]"
http://www.guru3d.com/articles_pages/nvidia_geforce_gtx...
Here is Guru3D's power supply recommendation:
GeForce GTX 970 or 980 - On your average system the card requires you to have a 500 Watt power supply unit.
GeForce GTX 970 or 980 in 2-way SLI - On your average system the cards require you to have an 800 Watt power supply unit as minimum.
If you are going to overclock your GPU or processor, then we do recommend you purchase something with some more stamina.
Remember this test was done with a highly OC'd 3960X .... (they can hit 230 watts) .... so adjust to your CPU accordingly.
3. Use a trustworthy calculator
http://extreme.outervision.com/psucalculatorlite.jsp
http://www.youtube.com/watch?v=Eqz4tDM6Wl8&index=1&list...
I would trust Toms and the 5 other benchmark websites that have put the 970 easily ahead of the 780.
Keep in mind that Linus does all his test with all cards overclocked "bawlz to the wall", Toms and everybody else does "outta the box" performance. You will also see the 780 topping the 290x for the same reason under their tests.
They also explain why the 970 doesn't overclock like the 980 / 780 Ti.

The 970 in SLI blows a 980 out of the water. It is a huge step up. I ran the figures on the PC PART PICKER and with two 970 sli I was still under a 550 w draw. As testing showed, they can draw a lot more then their ratings. Not sure it is wise to ride that close on the power supplies edge. No overclocking taken into account either.
I would agree , but I do think its possible if you have a good power supply.
