The card is good. But cable is better. For gaming, you want low latency and super-fast ping times. With wLAN, there are simply many factors that can have a strong influence on performance and over which you may have no influence, such as the wLAN networks of your neighbours. Depending on this, the frustration can be great because you expect too much and then realise that there are no miracles. Sometimes you have to try and tweak for a long time until you get it right. But if a cable is not an alternative, go for it. The card is in the high-end range. But if you have a router with WiFi6, I would take the AX58BT, also because of the Intel AX200 chip. In addition, the card can be configured more finely. With the AC88 you have a Broadcom chip and the drivers are, in my opinion, so la la. In my environment, the AX58BT offers significantly more performance than the AC88, assuming a WiFi6 router, of course.
