First build and a keyboard question

So I'm building my first gaming rig and am really excited, Ivy Bridge i5 and 560 non ti, (is that a mistake with the non ti? Should I return it and upgrade to the ti as it hasn't arrived yet?) but I digress. I know it's been discussed to death numerous times before here, and I've read the OCN Mechanical Keyboard Guide and the numerous threads here about the keyboards. I think I want the Cherry Brown switches as it will be used for both gaming and typing. I think I've narrowed it down to Rosewill RK-9000BR, the Ducky Shine DK9008S, and the Das Keyboard Professional Model S Silent. All three get good reviews for both gaming and general usage. So are these three good choices and between these three which one would be the best? Any other guidance or advice on the type of switch or other keyboards would be greatly appreciated. Thanks!
