A:Answer I believe it supports 3 displays. If you are looking for good 1440p gaming and decent 4k gaming this card is good. I would also look at the nvidia rtx 3080 founders edition if you can get one while they are instock. 4 displays isn't the best way to go. You could get a samsung g9, which is 49 inches at 1300 USD. I would also recommend a 6900xt if you really want higher performance. The 3080 and the 3070 ti have 4 display ports. The 3070 ti which provides low decent 1440p and high 1080p performance.
But for price to performance I would recommend a 6900xt (1200USD, Newegg) or the 6800xt (this one if you can get it.) Or the 3080 founders edition. ($700 USD Best Buy, goes out of stock really fast. It was instock yesterday for like 20 minutes.)
