Question Is SLI worth it?

[ch33r]

I figured out that I can almost get 2 RTX 2080s for price of 1 RTX 2080Ti. If I could SLI two 2080s, I would get about an 80% performance in SLI over one 2080Ti (I think). But I have also been told that many games have stopped supporting SLI, and that DX12 has very little, if no support at all for SLI. Can some highly experienced souls clarify the facts?

A 2080Ti is about 50% faster on average, and yes.
From the reviews:

• All games are set to their highest quality setting unless indicated otherwise.

Could a 2080 or 2080Ti take BO3 to 120 fps

 

[Gam3r01]

At 4k? You could probably get close at max settings, depending on the rest of the system specs.
If you turn down some settings at 4k, then probably.
1440p is easily doable.

Now is that for 2080 or 2080Ti. The system will have 3900X with 32GB RAM. M2 SSD. Even if I could get 1440p 120hz that would be great. Could a regular 2080 do 4k 120 or even a Ti?

 

[Gam3r01]

Im speaking only of the 2080Ti.
4k 120Hz would be doable at lower than max settings, probably somewhere around medium.
1440p 120Hz could likely be done at ultra or near ultra settings.

 

[ch33r]

So a 2080 wouldn't stand a chance then I assume

 

[Gam3r01]

Not likely.

Ok. My next question goes like this, and if it's too much to reply that's fine, because I think it might be a big questions, but how much FPS will I lose on average from turning on ray tracing? And is ray tracing just a gimmick or is it worth it?

 

[Gam3r01]

Yeah thats something Im not going to be able to answer, for several reasons.
I dont generally know the expected hit in performance, and I certainly cant speak for how it looks given I own an old AMD card and have never seen ray tracing in person.

Now, when you do the build, feel free to let us know how the performance changes.

 

[ch33r]

Those 2080 tests on texhpower up, did they have ray tracing turned on

 

[Gam3r01]

You would probably have to contact them directly to find that out, I dont consider RT to be a standard setting.

 

[ch33r]

Right ok I see. I understand. Ya I might get Ti. I'll have to think on that. At least I have something to go on now .... Loooooool

Question - Should I get a gaming monitor or a 55 inch 4K tv at 120Hz

Exactly as the title asks. The other question I have is: A lot of people have said 4K monitors/TVs will say 120 Hz, but they aren't actually 120HZ, they are 60Hz that use interpolation to guess the next frame. Which should I go for, and how do I know if my display will actually be 120Hz

Perhaps you might know this. I posted this. I don't know how well you know this stuff but you seem to know GPUs pretty well so I thought I would try

Ok, so the next question is: Forget 2 CPUs, why do we jam 8 cores into one CPU but apparently dual-core GPU is useless?

A GPU has hundreds to thousands of cores per die.
