If you live in the US then get these it's much better than a card, I have these in my house and it's very close to a direct line (always best to uses a direct line if possible)
They get plugged directly into the wall not a surge protector, one by the router and one by the PC. Plug and play no need to do anything else. http://www.newegg.com/Product/Product.aspx?Item=N82E16833704165
