Gaming monitor for wow

Hey guys.

I'm thinking in getting a 32" monitor. I was looking at really good reviews of the KTC monitors, and after a quick look found this one on amazon for a really good price.

Asking to the gaming gurus of wow, I'm a bit concerned about the refresh rate. This monitor have a 100Ghz, and my game is locked at 60fps. Read somewhere that the refresh rate in this case has to be a multiple of 60 to avoid any issues.

Can anyone give me advice based on your knowledge or own experience? Would I be fine with the 100Ghz monitor or I'll just have to aim a bit higher with a 144+Ghz one? I was also looking at this samsung monitor which is obviously a bit more expensive, I'm not necessarily on a budget here but I'm trying to save some money if possible. Would also be interested to know if there will be any considerations for other games that I should have to keep an eye when buying the new monitor.

Any advice would be highly appreciated.
