Network speed and ethernet cable questions with wifi card question

Debating on going wireless or not: Have an Asus M4A87TD EVO that has RTL8111E PCIe Gigabit LAN controller featuring AI NET2. So Gigabit, Im thinking at least 100/1000. I am wire into my router which puts out high speed and low ping to wireless. Standard Ethernet cables supply the data pipeline, not sure what the transfer speed is on them, If anyone can let me know that would be great.
I have been eyeballing the super speed ethernet cables, but not sure if it would solve the ping issues I have with desktop, (being too high), and the cost for a 15' line.
Tried finding a wireless card that handles N+network and 5.0Ghz for my dual band.

1. What is the standard ethernet cable speed?
2. Can the standard ethernet cable from router to computer be causing high ping? (have second computer with 3' cable, same issue)
3. Would it be better to go wireless and forego the wired ethernet cable?
4. What wireless card would you recommend?

UGH

1- what kind of cable? cat 5, cat5 E, cat 6?

2-Yes if cheap, old, or not shielded.

3-Not if you are transfering large amounts of data on your internal LAN

4-An 802.11 "N" card

Standard----Cat 5

Probably cheap - But then why does my wireless get fast ping when same type of cable goes from modem to router?

3-Not if you are transfering large amounts of data on your internal LAN
Given that HD streaming and Gaming I would say lots of data going back and forth

4-An 802.11 "N" card

As noted in the post I know I need a card that handles N network. My question was in reference to manufacturer, dual band card, 300, 600, etc

Your budget and needs?

No real budget, its flexible, dont want to overpay though. Usage is mainly going to be gaming, will probably buy two so HTPC can have good streaming netflix and other shows.

Note - must be 5.0 Ghz

Ethernet would be better for gaming but

Linksys dual band (up to 350 MB) tons of range, port forwarding for games, and secure.

Okay, I will look into that one then, thank You. The Ping Im getting is killing me on MW3

How high?

Ping between 520-580. even swapped for a cat5e with no change
