That is in and around my personal preference for the sort of upgrade one should take, 2x is a good factor of additional performance where you can get 60hz level graphics at 120hz or 60hz gaming in heavy games with some lovely graphics depending on what you want compared to today. In addition that extra VRAM will relieve some of the issues you are probably seeing in games like Shadows of Mordor.

its the exact upgrade I am considering now that the waterblocks for them are out.

Hmmm, ok. My dilemma right now is it the arctic hybrid cooler on one of my 670's will work on the 970.

Having just sold my 2nd MSI GTX 670PE 2 days ago I can tell you a Gigabyte GTX 970 G1 Gaming with 1554/8200 overclock is scoring 11500 in Firestrike. My 670's did 10700 and they too were overclocked to 1328/7100.
So only a minor increase in performance. So why did I sell the 670's? I prefer a more silent experience. The 970 at that overclock runs max 70 degrees at full load.
BTW I'm running a 120Hz monitor at 1080p which I will be using for the forseeable future.

I tested SLI 670's @1200mhz against both a single GTX 980 as well as SLI 980's and found that my two 670's were about dead on the same as a SINGLE 980 ... even beating the 980 in certain benchmarks.

SLI 980's destroyed the SLI 670's, obviously....

Here's the results (from an earlier post:

Like s1rrah and some others said, the performance is almost the same BUT
you will have more Vram and no microstutter or SLI compability issues.
The whole system might also run cooler and the power consumption will
be much better with one 980.

Theese would be the beating arguments.. or you wait one or two generations
longer and have some more performance like you would have now by buying
one 980 for example..


I´d wait and maybe get a 2nd hand 980 or 780ti for less $$$ in some months
instead of burning cash on new hardware to perform a sidegrade.

What smex said.

I think a single GTX980 would be the way to go. Sure you might lose a few points in some benchmarks, but the real world experience would be much improved.

Interesting. But wouldn't two 970 SLI's be more worth it though? Or that would just cost some real money?

Off topic: Hey smex, does your nick stand for scanmail for exchange? lol.

Two 970's are only slightly more expensive than a single 980 so that's the way I would go. You already have experience with SLI so you know what to expect.

If you're happy with how things run now, I wouldn't spend all that money just because my current cards were losing a bit of value.

Yeah, i haven't encountered any games that need more power anyway. I only game at 1080p 120Hz so I don't know if that matters. Well, wouldn't the cards lose more value in the future if I don't sell them now?

However if your issue with the 780 was that it wasn't sufficiently faster (and in the case compared to SLI it was often slower) then it would seem that the 970 or 980 doesn't bring a whole lot.

To really get the benefit from a 970 compared to a 2x 670's you probably need to get 2. 1 will be faster in some circumstances, it will be a bit slower in others and its sort of a side grade. Once you bring overclocking into the frame I guess the 970/980 is probably going to pull ahead as they overclock pretty well but is that sufficient for extra performance in your mind? Why didn't you go to a 780 is a mighty good question to ask yourself because despite a few extra features the 970 is around about a 780 - 780 ti in performance.

totally agree, a single 980/970 wouldn't be enough to replace what you have. 970 SLI would be where you would go if you want.

670 SLI with those coolers on them and good overclocks are sweet!
