RTX2070 v GTX1080ti - Which one?

[DerekSpeare]

So I'm contemplating an interim upgrade by replacing my GTX980ti (in a 5930k system) with either a 1080ti or 2070. The 1080ti has 11g ram and the 2070 has 8g. The 2070 has Vulcan and the 1080ti does not (as I know it to be). A new 2070 is about 500 USD and a used 1080ti goes for about 550-600. The 2070 scores a bit better on Passmark:

I'm not concerned about real time shading since my focus is on VR performance in DCS and other games. I'm also not sure if any game I use will use more than 8gb vram so 11gb in the 1080ti seems like it will go to waste. I'm on the fence, but leaning on the 2070.

 

I'm curious to know if anyone has gone from a 980ti to either 1080ti or 2070 and what their results are in DCSVR specifically (or other games like iRacing, Elite Dangerous or others in general).

 

Thanks for any points of view! :smartass::thumbup::pilotfly::joystick:

I have a 3930k chip with a 1080ti hydro 11GB. Coming from 2x680tis...huge difference. I run DCS on three monitors 5760x1080 with everything on max. If a mission has a ton of objects I may start to get a little slow down but i just go and drop a couple of things down one notch and all is good. I haven't monitored FPS in a while because it runs great so I cant give you fps counts.

Just a heads up DCS uses 6 to 8GB of VRAM in SP basic mission however when I go on line it uses 10+GB of VRAM. Now I don't know what happens if you have only 8GB of VRAM and log on to a MP server.

 

 

That said I did DCS MP when I had my 980Ti and well the 1080Ti really helped when derferred shading was set as default with early DCS 2.5.x.

 

Now in search of more performance I have upgraded to an RTX2080Ti

 

As for GPU a 1080Ti kinda fits in at the 2070/2080 level some things a better some are not so good depending what tests and which reviews you follow.

 

 

Here are some stats I put together not absolutes but it will give you and idea of performance

 

Bottom line the 1080Ti was very usable but new shinny thing won out. :)

<edit>

As I understand it Vulkan should be okay even on a 1080Ti system it's more about leveraging gains from multi core/multi threaded usage.

 

Some info here.

Looking at Nvidia's Vulkan driver download, there seems to be support for 1080Ti.

But it's a tough call. Ray Tracing doesn't come into the pictures since ED won't support it. But then I heard that 2070 has a faster rendering time. Which is very important for VR, one would think.

 

And 2070 has faster memory access.

 

Tough one to call. But if it were my money, I think I'd go with 2070.

pipped at the post,.. :D

 

As much as I think the 20 series are a tad over rated and a lot over priced I'd recommend going that way. TBH I'd also go for the 2080Ti but $$$

 

 

I'll just leave this link here, it might help to better understand,. :music_whistling:

I went for the 1080ti due to the 11GB video memory. No regrets so far :)
