Replace large 770 in mATX case with mini ITX-size 970?

post #1 of 6
Thread Starter 
Hi guys,

In January I bought a new CPU, mobo, and case to fit it all into a smaller Fractal Design Node 804, for various reasons. I really like the case and it's serving its purpose well, however my GPU was bought almost 2 years ago when I was using a standard mid-tower. It's the ASUS DCUII GTX 770. The twin fans expel air into the case, which used to not be a problem.

However, now that I've finished my Master's program, I've been playing more games and have seen that the GPU at times hits 80 degrees C. I'm worried that over time the extra heat will damage other components in the cramped case, and saw this ASUS GTX 970 small form factor gpu.

I'm wondering if the increase in performance (which I understand to be not small, but not very large either) combined with being more appropriate for my case would be worth the investment? If I sell my old card I could probably only wind up paying like $200-$250 for it, and I'd get a free copy of The Witcher 3. However, for probably 70% of my gaming (minus new games coming out this year and next year), my current card is graphically doing fine.

Or should I wait? I'm not sure if nvidia is coming out with a GTX 1080/1070 (or whatever they'll call it) this year, as I've been out of the loop due to school.

Thanks in advance for helping out.

If it's heat reduction you want, the 1080 or 980ti or whatever they end up calling it will not be what you're looking for. The power consumption of those cards will be higher than that of the 770 you have now, so even more heat in your case. A 970 is a pretty decent step up from a 770 while drawing less power, plus the new maxwell architecture seems to be getting a lot more love than the old kepler one in recent games, see this thread.

If there was any reason to wait, it might be that the new cards will make the 970 even cheaper as it will be lower down in the available line-up then, but if you have the money I'd say go for it. biggrin.gif

Hmmm, it's good to hear that. I'm probably going to pull the trigger later this week then. Are there rumors they will come out with a xx70 GPU again next generation though? Idk if it would be smart to wait for that.

The nvidia cards coming out later this year are all based on the GM200 die that the Titan X is based on that is already out, which means, like the titan, the actual size of the gpu die will be almost 50% larger than that of the 970 or 980's GM204.
It's less about the numbering as it is about what die the GPU is. Nvidia have been releasing their cards in a pattern, starting at least with the 600-series cards and continuing through the 700 series and now this 900 series, they first release the lower cost small-die cards (GTX 680 and 670, GTX 980 and 970) with low heat output, then later release their high cost big-die cards, based off of the same architecture, with a higher heat output.

I'm sorry if you were already familiar with all of this, just thought I'd try to explain it in case you weren't aware tongue.gif if you want to know more about GPU architectures and card models, have a look at reviews on sites like anandtech, like this one on the 980.

In all, the cards Nvidia will be coming out with will either be high-power, high heat output cards like the titan x, or they will be rebrands of the small-die cards of this current generation (the 980 and 970), just like the 770 is a rebrand of the 680.

I hope this is making things clearer for you tongue.gif

I wouldn't bother replacing it solely on heat. My 980 runs that hot when maxed out. If I put my fans on 100% its super loud, but it seeps down to about 68C. But thats on fans full blast. I would instead look at cooling your existing system better. Maybe changing your fan configuration to help pump out the GPU heat.

I'm not sure there is much more I can do in that regard. I have a fan on the bottom front bringing air in, and a fan in the back pulling air out, which is from what I've read a good configuration to have. I could technically put two 80mm fans on the bottom of the case to pull air out that way, but I would have to move my two SSDs down there to somewhere else in the case, and since it sits on the floor, there would be so little room for the fans to pump air into that I'm not sure it would make a difference. I have been meaning to buy a couple NF-F12s for my radiator though, and might as well pick up an airflow-variant noctua fan to replace the current fractal design ones in the case (which aren't that bad at all, btw).

Unless I'm missing something about fan configuration?
