Hello, I have a 24" 4K freesync monitor. I am looking to upgrade my GPU. My question is, will I see better performance at 4k with the 1080Ti despite not having adaptive sync or should I stick with an AMD product. I do not want to replace my monitor. My current setup is I5-4690, 16GB RAM, R9 290 4GB. I know the 1080Ti outpaces the vega, I'm just not sure if freesync will make up the difference or if it's worth the extra money. Thanks for all your help.
