First your router must support speeds that fast also. Next it will never run faster than your internet connection. So if you currently have a 84m connection and your current equipment runs at 84m the you can go no faster.
Last and most important games use very little bandwidth. Most use well under 1mbit/sec. The game companies want people who have extremely slow internet connection to still pay them money so they design the games to use very little bandwidth. So a really expensive network card will not improve performance.
What is also important to remember wireless is the worst possible network choice for games. It will have random data loss and delays which games do not tolerate. If at all possible use a ethernet connection. If that is not possible consider powerline networks instead of wireless.
Bill, this is wildly incorrect.
Wireless is perfectly fine for gaming provided you get a decent adapter.
"It will have random data loss and delays which games do not tolerate."
You're referring to packet loss, which is either due to inconsistencies in connection, (not client side dropout) or server side issues.
"Last and most important games use very little bandwidth. Most use well under 1mbit/sec.

I don't even know how to respond to this to be honest, it's just that dumbfounding.
🙁
Please read up on how the internet actually works, what network latency is, and what network transfer rates are.
This is all 100% false, ignore it OP.
An expensive network card will have better support for higher bandwidth connection standards (e.g. 802.11ac) and will feature higher end components to better relay the signal to your PC.
See the links above for your two choices OP, make a decision based on aesthetics and run with it.
