hi, i recommend this monitor https://www.amazon.com/GN24C-Monitor-Bezel-less-Samsung-Speakers-Full/dp/B078P2XN9M/ref=sr_1_1_sspa?s=pc&ie=UTF8&qid=1518398410&sr=1-1-spons&keywords=144hz+monitor&psc=1
but if thats to expensive this one. https://www.amazon.com/Acer-GN246HL-Bbid-24-Inch-Display/dp/B00KO4518I/ref=sr_1_3?s=pc&ie=UTF8&qid=1518398410&sr=1-3&keywords=144hz+monitor&dpID=51aitVb-dXL&preST=_SX300_QL70_&dpSrc=srch
I dont think 144hz is overkill, i used to have a 960 2gb and only a I3 and was able to get 144 fps easly in games like csgo overwatch unturned rocket league mine craft and stuff like that. good luck.
