You'll have substantially better results from modern integrated graphics (even on the low-end Intel UHD side). This is genuinely the card you get if you just need the extra outputs and don't care about performance, or you have a CPU lacking integrated graphics and don't care about performance.
In other words, there are use cases for it, but I absolutely agree that a gaming card this is not and it has a very specific niche.
Yup, addressed in my original reply.
