I recently read that a 4K monitor is better served by a 1080Ti rather than a 1080 GPU card. But I've also read that UHD is not a native resolution for FSX or P3D therefore rather pointless.

Either I've misunderstood (most likely) or just a bit confused as the price for the 1080Ti is considerably more than the 1080. Clarification please as I'm putting together my next gaming spec PC. Thx

I run a 1080 on a 43" 4k Samsung TV and it works just fine for P3d, X-plane, DCS and every other game I have.  Using 4k, you can usually turn your anti aliasing options down since there are more pixels to render the shimmering is nowhere near as bad as at 1080p.

I run a ASUS 4k monitor and in NVidia control panel have enabled 8bit UHD running on an MSI 1080 gamer Plus, no problem FPS lock at 30 stays above 23 in high detailed airports.

Will the 1080 be sufficient for a 40" 4K Samsung with an I7-4790K?  I've been stalking the 1080ti but it's expensive and out of stock every time I get a notice that it's in stock...
