gtx 970 vs gtx 1070 upgrade

Solution
Seeing how the 1070 is not released yet, it is too early to say. The 970 is a good card and you are probably going to be better off sticking with that for a couple more years.
Yes. Provided it's at least 2.3% faster, or has pink unicorns.

Seriously though, my personal rule of thumb is a 2X increase in performance but for others I suggest maybe at least 1.5X increase in performance. I'd be surprised if the GTX1070 (or similar) is more than 25% faster going by past numbering.

You may even want to put your money towards a GSYNC MONITOR if you've not got a great monitor. (Expensive and I'm still waiting though I have a nice IPS 1440p model)

Also, you can go a long, long way if you know how to tweak. I've seen plenty of people have worse gaming experience on better systems than mine. Things like:

1) VSYNC ON (yes or no)
2) if yes, then maybe ADAPTIVE VSYNC?
3) If adaptive and 144Hz monitor maybe force the "HALF" method to get 72FPS?

Basically if you go with VSYNC OFF you'll get screen tear but can just aim your frame rate by tweaking settings to get say 50FPS or whatever average. With Adaptive VSync it's trickier. I aim to rarely drop below 60FPS (60Hz monitor) but when I do I just get a bit of screen tearing as VSYNC is auto turned off.

You don't want VSYNC ON then drop below the target as it causes stuttering (varying frame times).
 
The 1070 has 2X as much VRAM as the 970. the 1070 has 8GB VRAM where the 970 has 4GB. The 1070 has the same amount of cuda cores as the 980. http://wccftech.com/rumor-nvidia-pascal-gtx-1080-gddr5x-gtx-1070-f-gddr5/
 

it's on the same site tracking radeons new GPU, though this information is not posted everywhere, you can't accuse me of spreading false info as you your self have no way of fact checking it past what anyone else can. So maybe say this info might be false rather than saying because there's no proof it is false, because neither of us can provide hard proof as no one can on either side.
 



WELLLPP FASTER THAN TITAN X SOOOO YEAHHH ITS WORTH IT IMO i have a gtx 970 anyone wanna buy it plss asapp LOL
 


thats in VR. need to wait for real benchmarks to come out but man im excited
 
I dont see y so many people upgrade if they dont even have a 144hz monitor. The ram on the card dont really matter if u play at 1080. most people only play at 1080 so to upgrade from a 970 is pointless. Im still using my gtx 760 with no issues lol
