Hello guys, I am wondering if I can use the full potential of double 2080Ti, with a i9 9900k, asrock z390 phantom SLI/AC, and 32Gb RAM DDR4 2666. I have been reading about the PCIe lanes and stuff like that, but I can’t fully understand it. Thank you in advance

The GPUs will run at 8x which is still fast enough to carry the full strength of the card through, however you will be limited like crazy with SLI as it doesnt scale well, if at all and with a 2080ti, you have enough horsepower to drive AAA games at 4k/60fps.

Assuming that cpu can handle the games you plan to play and the frames those cards can support.

Your main issue will be SLI lottery. Its a giant gamble with NVLink because some games will scale well, others will work like trash.

 

Read this thread and forget about 2080ti in SLI please.

No, because SLi/CF doesn't work with most modern games...

Onyl ah hand full modern Games support that.

I will be doing 2080 ti NVLink when the top next gen card come out since I already have 2. 

 

If I didn't have two I would not buy one for SLI unless I played a game or a sim all the time that supports it.

 

I have over 5000 hours on one game that supports SLI and I needed SLI(1080 tis) to stay at 4k resolution.  My 2080 ti performance in that game is not good as it was with two 1080 tis. Instead of getting a third 2080 ti I bought a 3840 X 1600 monitor for close to the same amount of money and that is a good size for a single 2080 ti. 

 

In the tests that I have done a 5ghz CPU is need to not bottleneck at 1080p and 1440p so only the i9 9900k stock can run one full out. I think any CPU overclocked to 5ghz can.

 

In SLI/NVLink at most you get 75% out of the second card. That was how it was with my 1080 ti SLI and 980 ti SLI so no you will not get the full potential but it will be close enough at 4k if the game support it.

Sucks neeeding such a strong cpu to enjoy the benefits of sli now. Past decade has been quite fun but seems like that’s all over now. Single card pleb life leaves nothing to be desired.
