I built this as my first gaming computer not too long ago, but I feel like its time to upgrade some of the parts. I am still learning so I could really use some advice on what needs to be upgraded and what doesn't. I use it for pretty basic gaming, WoW, LoL, CSS and BF, nothing really intense. However I am using a 24' monitor and I am about to get a second 24' monitor, I would like to be able to play games on one monitor and keep a web browser or whatever open on another. So two monitors with great resolution and no lag is my goal, ill list my build below, if anyone could point out or suggest changes I could or need to make this happen I would really appreciate it, remember this is my first build and just learned it all myself as I went so I am sure its not the best, but its the best I could do learning on my own from no experience.
