what is the latency of wifi these days? it's the one part i've been missing from motherboard reviews...and come to think of it i don't think it was mentioned in the XR500 router review (which i now own since good reviews and the modem/wifi combo from the isp was annoying me with modem crashes and it makes for a decent on the cheap media server when your to cheap to buy a NAS or something 😛).
the throughput these days seems impressive but how much does modern wifi add to the ping compared to the 0-1ms of a cable.
i've been considering getting a higher end mobo with wifi built in so i could eventually get rid of the 20m of cable i've poorly hidden through the house but i do game a lot and wile cable is still ofc king but has wifi reached the "eh ping difference is so low it kinda doesn't matter if you do it right" point

Not for gaming, but interesting for those (like me) with fiber connection (1gbs down - 600mbs up).
Wifi is still the bottle-neck for streaming / downloading.

With a low load, you're talking about 0-1 ms. This number can greatly increase, the more active clients you have.
Now with 802.11ax is a new standard added to the Wi-Fi standard (sadly only for 802.11ax APs and clients), named DL-OFDMA. This is BY FAR the most important addition of 802.11ax, as it allows real QoS (time reservation for important applications).

Lol for that comment.
My roommate is running wifi b/g single band router floor below and i have 10 to 12ms, most of the time around 11ms connected to the game server, when wired gives me 9ms as the lowest ive seen 8ms.
And by the time its a bottleneck for bandwidth, your not one of the +80% of the market anyway, and your most likely not using it for gaming alone.
Friends have 1Gbit speeds and wifi is maybe a few hundreds slower, while ONE router for 10 devices is in the basement with concrete walls.
I guarantee +90% will have added input lag around 20 to 30ms just because of the fact they are gaming on tv, and/or wrong settings for win/tcp etc.

I've considered building a server rack to cram all of my various PCs in while using my laptop and TV as thin clients, and use an ad-hoc wifi connection to stream the display and audio. That way I don't have to deal with the noise, exhaust heat, and cables of all those computers in my living space, and since the connection is ad-hoc over a different frequency range, there shouldn't be any issues with interference or bandwidth being choked. Each of the computers in the rack could be connected via Ethernet, so file transfers between them will be very fast, and again, without messing with the wifi bandwidth.
As stated by pato, it's highly variable. The more clients and just general interference you have (whether that be EMI, other wifi networks, or walls/objects blocking your signal) the worse your ping and overall bandwidth is going to be. Seeing as you already have cables laid out, I'd recommend you stick with it if you can tolerate it.

I was playing some games through Wifi N and I don't really feel the lag though... of course, wired is the best option, but I don't feel there's a big difference between N, AC, and AX... maybe it's just me...

Don't forget, the client also must support the 802.11XX standard. So if you have an 802.11ac Wave2 AP, then the clients also needs to support that, to profit of the new features. If you have an older client which is transmitting data, then the speed drops back to the lower standard for that duration.

The pure latency is fairly OK these days, but it's the spikes and inconsistencies that are the problem. Also depends on how many Wireless devices are being used at the same time. You could also give powerlines a go, but I'd go with decent brand such as Devolo.
