I am buying a new PCIE lan card but I'm confused which one to buy, which one could give me lower ping and better reliability for lasting long time

The thing I'm interested in micronet lan card that it has Integrated 128KB Frame Buffer Memory+more 2xexpensive then tp-link TG-3468 card...Tp-Link lan card has 20/200/2000Mbps Full-Duplex mode+ better brand + have latest driver software support. I just want lower ping for 24/7/365 online gaming
