One RTX3090 vs Two RTX3080Ti's

[ducaud 9]

Hello,

I have build up a new system to run P3DV5 and MSFS 2020. I have an I9-10900K, 32 GB of 4000 Mhz RAM, 3NVME's.

I am planning on getting an RTX 3090 preferably one with the clock around 1800 Mhz. I have lisyed myself in all the notification emails of all the vendors to see if I could get one.

Now I am reading the Nvidia is releasing the 3080 TI which will have 20 Gb of VRAM memory. for around $1,000.

My system currently is using an 1080ti and I have three 2k screens, so is 7680 x 1440.  I have my monitors set at 30Hz,  The visuals are pretty smooth and very seldom goes down below 30 FPS. 

The major issues I am experiencing are while turning while taxing and panning on aircraft outside views. I would also love to increase the distance that the scenery and the vegetation pops up. 

What would work better specially in terms of P3DV5 one RTX 3090 or 2 RTX 3080 ti's

Of course that I can get my hands on them sometime in the near future.

Thanks

Juan

The last I heard was that SLI was troublesome. My vote goes to one RTX 3090.

I don`t think the 3080ti will have SLI only the 3090 is SLI compatible intended for developers not for gaming.

SLI can be a real bucket of worms...in my experience (with 2x 980Ti and 2x1080Ti configs) some drivers were a real mess with SLI, and even today, some software does not work correctly with it (Reallight/Trueglass, GSX/GSX2 as examples).

When I moved from a dual 1080Ti config to a single 2080Ti, there was a small performance bump, but the reduction in the hassle factor from going to the single card was well worth it.

I wouldn't recommend SLI for general use in a simming platform any more.

Oh yes, thats right. 3090 only. Not sure if it will apply to the ti version too. Probably will.

Thanks for the replies guys. I have  read that the SLI can be a pain.

I am now using a 1080 ti with surround for three 2k monitors, and even using the wideview correction the image is quite stretched on the side monitors.

I was thinking on using multi cards using viewgroups. Maybe 3 RTX 3070's which have 8 gb each connected each to a monitor. would that be better than just one 3090?

Thanks

I'm also in the camp of just going single card.  Regarding vegetation/scenery appearing earlier.  IMO this is primarily affected by your processor and not GPU.  Of course customized via the settings menu

You may find out more about the upcoming new GPU`s next Tuesday.

Looks like some things never change. In 2003 I built a rig with 2 Nvidia 6800GT's sli and it was a complete waste of $$ and effort for several reasons, but mainly because sli was/is buggy. I never say never, but I will NEVER use sli again.
