Need a good keyboard and mouse

I have recently built a PC and I need a good keyboard and mouse. There a just SO many. Any suggestions are appreciated.

I like razor products personally but what ever brand you go with get a mechanical keyboard with cherry switches. 

I was going to get the Coarsair K70. Here's the link:http://www.newegg.com/Product/Product.aspx?Item=N82E16823816010

Do you think it's worth it?

I have a K70 and I love it, no regrets at all.

So, that's the one then. Thanks
