VAU23 I apologize for the late reply. I've been away from the forums for a while and am only now catching up with older threads.
The PC you linked isn't any faster than the others with an RTX 4060. The processor is a bit better than some of them, but that should make only a minimal difference, if any at all, at least as far as Sims 4 is concerned. The game can use only four CPU cores, so the extra cores above six (for multitasking and background processes) don't help at all.
For the monitors, the first one is clearly better because it has an IPS panel, which is the highest quality in terms of color and viewing angle, although VA (the other monitor's panel type) is fine if IPS isn't in the budget. But the first one is also cheaper and has a higher refresh rate, and they have the same resolution, and they're both made by a reputable company, so there's no reason to get the second.
However, I would suggest looking into QHD panels too, especially if you like having the game look crisp and clear. The extra pixels can make a big difference, and an RTX 4060 can handle the higher workload without any trouble. Beyond about 120 Hz, the higher refresh rate doesn't make nearly as much difference. You could probably tell if the monitors were side by side, but only by looking closely, and Sims 4 has trouble running at high framerates anyway. It also has a default fps cap of 200, which can be lifted if you want.
If you'd still like help picking out a monitor, let me know.
