It is, but not 1440p at 144hz. 1440p at 60hz or 1080p high refresh are feasible. Nothing wrong with over-buying with a monitor. People tend to keep them a lot longer than GPUs. (I have a GTX 1080 and a 1440p @ 144hz monitor. Plenty of older games I get decent frame rates, but games like BFV, more like 80FPS, though that was the Beta and a while ago)

If we take FarCry 5 and BF1 (as a stand in for BF5) you can see it will keep it above 60 FPS at all times, but not creep up to 100+ FPS very often if ever. On the higher settings anyway. You can certainly tweak it to your tastes, but benches are typically run to show card comparisons.
For scale:
1080p @ 60hz 124,416,000 pixels per second
1440p @ 60hz 221,184,000 pixels per second
1080p @ 144hz 298,598,400 pixels per second
3440x1440 @ 75hz 371,520,000 pixels per second
3440x1440 @ 100hz 495,360,000 pixels per second
4K @ 60hz 497,664,000 pixels per second
1440p @ 144hz 530,841,600 pixels per second
4K @ 120hz 995,328,000 pixels per second
Additionally, memory requirements go up as resolution increases.
