Dual GTX 970 SLI or Single GTX 980
2 x GTX 970 = 1 GTX 980 + a little. Should I pay a little extra cash to get dual GTX 970 or stick with single GTX 980? Assume power consumption is not my concern.

in theory yes, however SLI on 970s are unstable right now at stock voltage and very unstable with even minor over clocking due to massive bug. I know, its what I roll and im about the put the 970s cards on ebay if I cannot get a refund. Sadly even setting manual voltages boost dosn't always work either and once you get a driver crash, a restart is needed to manually set the voltage again. Very annoying.
BTW each card is 100% stable with boost clock of 1400mhz and in SLI, so I know I have 2 good cards. The voltage dip is 0.1-0.12volts, this is more than you can boost in the software, so perfect stability is impossible.

Gone back to my 660ti SLI for now, while I consider which single 980 card to go far.

Pretty much every single modern game works great with SLI and it matters huge what resolution is being played. Sli'd 970`s blow the 980 out of the water, and if you are playing 1440p or 4k you will need and want the extra firepower.

Here is a link to some benchmarks....

My Sli 970`s work fine on every game that allows SLI.

Since GTX 970 SLI~GTX 980(difference is only about 5-10 FPS difference at most(in favour of the 980)),go for the cheaper version.



.... Um.... Nuh ugh... Gtx 970 sli is very close to the r9 295x2... The 980 is a very good single card.... But only about 5-10% more "powerful" than a 780 ti

I'm in the same boat. Since I purchased my 780 (which at the time I thought was going to be overkill), I have found the wonders of 3D gaming. I'm still just playing at 1080, but the extra FPS can certainly be used in getting the games closer to the magic 60 FPS (and possibly with settings on high!) in 3D.

Gotta love the new options from NVidia...

Thank all - I will either go with GTX970 or Dual GTX970 SLI.
@sla70r - thank for the SLI benchmark. I could not find any comparison between GTX 970 SLI vs others. They are only single card reviews.

Doesn't matter if it's 1080p or 1440p or 4K.
He should get the cheaper version.
SLI/Crossfire is used for multi-monitor setups and workstations.
Video games are not optimized for SLI/Crossfire configs.
