980ti SLI or 1080?

Recommended Posts

Hi to everyone!

 

Im having a first world problem, should i get another 980ti or roll over to a single 1080? I run a 49" 4K tv locked a 30hz.

 

Would SLI scale accordingly?

 

Thank you for any help or advice in advance.

No, SLI does not scale "accordingly", means: you will get more FPS in P3D thanks to SLI, but far away from what you get in other games/software. Maybe 20-30% more? I guess, others can give you more precise numbers. Those 20-30% more is exactly about what you get when you replace the 980Ti with a 1080. So, in my opinion, going to a GTX-1080 would be the better of those two solutions. But first, I would definitely test your current performance at 4K with your current setup, you might even not need any upgrade at all. Thanks to DSR, you can already now select the 4K resolution and see how your rig performs.

1080 without doubt... but the price is a little meh atm. The next month the first AMD will be available, and maybe the price of the 1070 will drop a little, and subsequently the 1080 as well.. so I would wait 30 days.

Hi, thank you for your responces. I already have a 4k monitor and P3D runs very smooth locked at 30hz. Was really looking at getting some more "grunt" in the clouds especially during overcast conditions.

 

I really must update my sig, sorry if it was misleading.

 

Regards

Do you use SGSSAA? It might worth to test if you are not happy with the "normal" antialiasing modes, as SGSSAA is extremely heavy in cloudy conditions and not really needed on a 4K display...

Buy anonther 980Ti. You can pick up a used one for around the same as upgrading to a single 1080 which won't improve much at all.

Thanks for your help on this matter, looks like im leaning to stump for another 980ti. Most of the 4k tests i see with 980ti SLI are 20% better than a single 1080. I understand the pros and cons of SLI now, however in the next month or so i think the 980ti will drop in price as board partners bring out their 1080s. Its about the bang for buck!

 

Kind Regards

I just recently went with 980Ti in SLI and with sliders almost all right and really bad weather (from P3D itself) I got about 25-30% increase from non-SLI.  It actually surprised me that it was that much.  I had just bought everything for my SLI setup, including motherboard (basically I ended up build a whole new computer), when the 1080 release was announced and was worrying if I had made a big mistake.  So far I think I'll be OK, at least for quite a while.  It's running very well.  Now, the 1080Ti might be a different matter, especially in SLI.

The extra 980Ti won't make much if any difference to frames; I had two in SLI and ended up selling one. Also consider the additional power consumption, and note that significantly more heat will be generated inside your case by having two cards very close together. The 1080 will use less of power than one 980Ti and run cooler.

I disagree with this whole heartedly. Two 980 Ti's in SLI is significantly more powerful than a single 1080. SLI is has been shown to improve frame rates by a good ~30%. Have a look here, great work by Rob A.:

If you decide to opt for SLI... make sure you have a power supply that can handle the extra load!

SLI will probably have marginally faster performance, but it comes with it's own issues. A 980Ti is very close in performance to a 1080 so I wouldn't suggest an upgrade (unless of course money is no issue, but then why would you ask). My advice? Save your money for the big Pascal chips (1080Ti/pascal titan) with HBM2 coming in early 2017.

For some AAA titles that is certainly the case, but in the context of P3D I don't believe SLI represents good value. Just my 2c as a former SLI owner. ;-)

Hi all,

 

Thanks again for all your advice and views. Ive opted for a 1080. However as a twist ive decided to sell my system and build a X99 Broadwell E based one. Lets see how it goes.

Which Broadwell-E CPU?

 

In regard to Broadwell-E, some may disagree, but I don't think you will see a significant difference in the sim for gaming. Thus... it could be a huge waste of money given the crazy high cost of the CPU.

 

I would do some very careful research. 

 

IPC is minimal compared to Skylake.

The new Skylake's use Broadwell and X99 motherboards. I want someone to go nuts and get the 10 core/20thread 6950X for $1600 :)

I should edit my post above. When I say IPC is minimal compared to Skylake, I mean there's a minimal "difference" in terms of IPC.

No, Skylake is Z170 Brian. Unless you mean Skylake E, and I don't think we have any idea yet what's happening with that.

And the claim is that the bigger cache and more cores will make a worthwhile difference in P3D. I'm doubtful of that claim. And in terms of the HUGE cost of the 6950X I don't believe there's any way it's worth it. I would contend that there would be barely any difference between Broadwell-E and Skylake.

Maybe so with P3D, but I use my computer for 2 things. P3D and as my main brain in for my audio production/studio. Those 10 cores would make my rig a straight-up beast in Pro Tools.

Hi, I was looking at the 6900k for 8 cores. The rational is more room to off load OBS, ASN etc, and give more cores to P3D rendering. Looking at Rob As videos P3D is multi-core aware thus helping with smoothness and sharpness of terrain. I'm running 4K locked at 30hz so I'm hoping a little more grunt will keep me above that magic number.
