Killer N-1103 Wifi

Firstly I'm Sorry if this has already been asked elsewhere on the forum...

So I've ordered the M17x R4 and one of my custom upgrades is the Killer N-1103 wifi card. What I want to know from you guys if possible is, what wireless router do I need to get the full benefit of having this card? Obviously I know I need a good broadband speed in the first place but what do I need between that and the killer card to make sure I get the best performance from this component?

Thanks in advance...

I should add that my current router is a wireless G so I know I need to upgrade I just need to know what's the best way to go?
