Cat5, Cat5e and Cat6e Which is good for my gaming experience?

Hello Community, I did a lot of research past few weeks about the Ethernet cables available in the Market, but the more I was Researching the more I got Confused in the Categories they offer. Till Now I have got to these points.

The Major Types Of Ethernet Cables Available in the Market comes from the different Categories -

1) Category 3
2) Category 5
3) Category 5e
4) Category 6
5) Category 6a
6) Category 7

The Maximum Data Transmission speed of the Category 3 Type of Ethernet Cable is 10Mbps and the maximum Bandwidth it can handle is 16Mhz. Category 5 Ethernet Cable Transmission Speed is between 10-100Mbps and the maximum Bandwidth It can handle is 100Mhz. The same goes for Category 5e but bu the major difference between Cat5 and Cat5e is Transmission speed, the transmission speed increased to 1000Mhz.

Category 6a and Category 7 both have same Transmission speed which is 10,000Mhz but their Bandwidth is different, Cat6a has 500Mhz and Cat7 has 600Mhz.

I am big gaming geek, I need unstoppable surfing while I play large Bandwidth Games, SO I Want an Ethernet cable that Provides me Non-Stop Surfing Because I heard from here that bad ethernet cables can give you Poor Results, I don't  want that Please Help me out in getting the perfect one and educate a little more about the differences.
