1070 ti SC enough?

BCJM76 · Sep 15, 2018

So, as the title states, I have my eye on a GTX 1070 ti SC. I'm worried about my current GTX 1060's ability to run ACC in VR without having to drop the visuals down to low just to get a decent frame rate.

I can currently play AC on high settings in VR with little problems and get a pretty stable frame rate between 60fps and 70fps. Project cars 2, however, I do have to drop the visuals to a mix of low and medium to make it playable for me.

The question I guess I have is, would it be worth it for me to get a 1070 ti, or would I be better off waiting for black Friday and hoping I can score a good deal on a 1080? Going with the 1070, I wouldn't have to swap out my psu, whereas I would with a 1080, which would add to my costs.

Any opinions? I would also like to future proof my system for at least a few years.

What's your PSU?
If memory doesn't fail me, in regards to power draw, GTX1070 and GTX1070Ti are 170W~180W, and GTX1080 is ~200W. Difference in power draw between them seems somewhat small (600W+ PSU recommended for all three, I think?).

If you have set your mind in either 1070Ti or 1080, then (IMHO) I'd definitely wait for Black Friday deals and get the best GTX1080 you can find for your budget then.
Although the investment is bigger, it also justifies it better over your GTX1060.
The GTX1080 is (at least) 10% faster than the GTX1070Ti, and (at least) 20% faster than the GTX1070. It also overclocks better (and has pre-overclocked models available, whereas GTX1070Ti doesn't), and also has high 2nd hand appeal and rating (so, better if selling it later).

And, who knows, at the time of BlackFriday (late November?) when the RTX2070 will have over one month of market, and plenty indepth reviews, there can be equally nice deals for it too....

My psu is 500w. Everything I have read reccomends a 500w psu for the 1070 ti and a 600w psu for the 1080.

I recently built a pc with a 1070ti, for assetto corsa.

It runs ACC at more than 70-80 fps with about max graphic settings in all the situatin i have tested (race with 19 Ai)

I have a i7 8700k and 16 gb ram.
I also have a gsync monitor 2560x1080 ang the game is 100% fluid.

My two cents if it may help, without any contractual garantee

That's a line the reviewers draw (for PSU recomendations) that isn't really precise or 100% valid for all user case scenarios.
It may or may not be enough. First, because not all PSUs are equal and, second, because 500W is unlikely to be enough for all user case scenarios.

A 500W PSU will be close to the lowest limit the GTX1070 can accept. You're likely to be limited to vanilla spec models with a single 8-pin connector from the PSU ("FE" and models based on it), because it'll be the most economical (relatively) in power draw.
Some GTX1070 models have 8-pin + 6-pin connector, usually for overclock purposes, and draw more power. These may be starved if on a 500W PSU.

Trying to ilustrate what I mean, I'll list Guru3d's power draw info for GTX1070 and GTX1080:

GTX1070 FE - 161W (see here)
GTX1070 GamingX - 186W (see here)
GTX1080 FE - 184W (see here)
GTX1080 GamingX - 198W (see here)

In regards to power draw, while there is a difference from the GTX1070 FE card to the GTX1080 GamingX, there is no difference between a GTX1070 GamingX and a GTX1080 FE.
This is somewhat logical, non-vanilla models like the MSI GamingX allow more room for overclock and so need more power. So it kinda puts the GTX1080 in same power draw area.
As for the GTX1070Ti, it sits between them, so same situation applies.

I hope it now makes more sense why most recommend a good 600W+ PSU for all these GPUs (GTX1070, GTX1070Ti and GTX1080), simply for a "one size fits all" aproach.

But better just do your own estimations based on a PSU calculator for your system, I think?
For that, perhaps check these:
