If you are looking to upgrade your monitor, I would recommend this one without hesitation. It doesn't have all the bells and whistles as some of the more expensive monitors on the market, but for the price of about $225-260 you absolutely cannot go wrong with the CTX X701A.

It is cheap, at 14ms response latancy it is a very capable gamer, did I mention it is really cheap? This will be one of the smartest investments you will make for your desktop.
