New to Prepar3d- Video Card upgrade time

[ChrisDa 41]

Hi Guys,

I have just finished building my new rig, almost the same as the OP's.

Gigabyte Z370 gaming but with a i7 8700k.

After a lot of research, I settled for the nVidia1070Ti Foundation Edition.

Research showed that to move up to the 1080Ti, the cost penalty of an extra 45% showed only a 2% performance improvement.

I have the 8700k overclocked to 5ghz, but can obtain 5.2ghz but there is instability at those clock rates. All ok doing the bench marks at 5.2, but P3Dv4.4 doesn't like it.

I have only a few ORBX products installed so far, with more to go, but I'm easily getting 40FPS just about everywhere but suffered a big drop to 25FPS flying into FsDreamteams KLAX in PMDG's 737NGX.  

Overclocking the Z370 is dead easy with only a couple of settings to tweak.

Oh, BTW, the i7 is liquid cooled.

Chris.

How did you calculate the '2% performance improvement'?

Memory Bandwidth of 256 GB/sec for a 1070Ti compared to 484 GB/sec for a 1080Ti is nearly 90% better - that's a lot more data being processed in the same amount of time.

No, I didn't calculate it, it was a direct quote from a website that did an extensive review and bench testing of the nVidia GTX 1070Ti Foundation Edition.

Don't ask me where as I did a lot of research on the subject.

Chris.

Not trying to butt in, but I am running a 6700k at 4.7. OC, I have a 1080 (non Ti) and am perfectly satisfied running at 4k with single monitor at 30hz..... except with overcast condition with AS. I'm ready to bite the bullet on a 2080ti if I was certain it would greatly help in that situation. Any thoughts?

I have your exact specs...6700k @ 4.7, 4k 30hz tv, went from a 980 Ti to 2080 Ti and don't regret it. AS weather can't bring me below 30fps, only dynamic lighting at payware airports on occasion if my settings are high and I'm flying into a big event on Vatsim or something.

If one can get hold of two used 1080ti a 2-way SLI configuration using 1080ti is much faster than a single 2080ti, given the CPU is capable.

I believe several reputable testers have found the data supports the opposite.  Unless of course you have data to support your view?

I bought a 2080ti partly on grounds it is actually more cost effective than twin 1080ti's and has none of the SLI drawbacks.

Same here, 8700k, 980ti to 2080ti, no regrets :) (apart from the beasting I'll get if my wife ever finds out!)

Wow you guys are clearly more into this than I am, which is 1.  Awesome....and 2.  I'm jealous.  Kevin, I hope your wife doesn't find out, but if she does, I'll buy the 2080ti for a good deal. 🙂

 

What would just going to a 1070 ti do for what I mentioned above?  I just don't think I can afford to fork over that kind of dough for a 1080ti or 2080ti.

Neither did I, but I didnt want to regret my choice and spend the next few years wishing I'd spent a little bit more....

You are right, I cannot prove it because I don't have a 2080TI, but I can tell how much fps raised when going from one 1080TI to an SLI configuration. SLI makes best sense when a scenario is GPU bound, GPU load 90% upward (this means 8xSSAA).

 

With this settings, using the Carenado Cessna 152 II at ORBX LOWI (no AI traffic, but overcast with rain😞

 

https://www.dropbox.com/s/opcefhdt7p4yhpy/Settings.jpg?dl=0

 

FPS went from 38 to 72. In addition GPU load went down from 99% to 96%. Is a 2080ti capable of doing that? If yes, how cool must a 2080TI SLI configuration be? In the SLI configuration the GPU load value is from the first card, second is lower.

 

Here is an Excel table of the FPS and GPU load values for all AA settings (same Options settings as in the pic above, no AI traffic, but same weather as above):

 

https://www.dropbox.com/s/6ayjg6vji8sfp9j/1080TI SLI.jpg?dl=0

 

This by the way shows that the setup with 1x 1080TI was clearly GPU bound, regardless which AA setting I used. The SLI setup tends to be CPU bound all over.

 

I did those tests just some days ago before and after upgrading my rig. Looking over the SLI FPS values I now was wondering if those multiple values in the low 70s for SLI fps are ok or if I made a mistake. So i redid the test just now and yes, it is like that.

 

And here is a picture of the test scene:

and.. my wife doesn't know about the 2nd card.....

a 2nd 2080TI....

[bbain1187 118]

I'm definitely CPU-bound now with my 2080 Ti. I've read the 10-series Intel CPU's will be out this year. Better start working more overtime.

I also did some tests with Dynamic Lighting. Here are the results. (I did not do the test DL + weather + rain for 1 1080TI before I upgraded to SLI, just for clear weather).

So after looking at video card benchmarks......I'm still left with a few questions.  I do know that everyone is different, and everyone's budget is diff.  I know I'm not going to get 80+ FPS and everything perfect, but I also personally can't drop $1,000 on a video card.  (Yet I will burn a $5 cigar with no problem.)  So go figure.

 

Anyway.....what would be wrong with a 

 

RTX 2070

RTX 2060

GTX 1660 Ti

 

These cards are ranked in the top 30 overall, I just don't see how they wouldn't be a vast improvement of what I'm currently running.

[DellyPilot 109]

I can highly recommend the 2080TI 🙂

But seriously any upgrade you will notice. In most situations the biggest impact will be your CPU. Ideally you should get a 2070 with a 8700K or better still an i9 9900K.

Really most of the performance improvement I saw was moving to the 9900K. Problem is then you have to get a new MB and RAM so it adds up quickly.

There are no easy answers but a 1070 would be an awful shame. Better save up another few 100 bucks (wait for P3D v5) and get a RTX2070.
