This is my first time attempting to do something like this. It has been something i always wanted to do because I love to play games. The only games i will really be playing are games like WOW, Diablo 3, Starcraft 2, and Civ 5. I would also like to have multiple screen capabilities somewhere down the line because that is really cool. I have been researching for weeks now about the different CPUs, GPUs, and all that but I don't want to put in too much power where I don't need to. I'm pretty cheap so I am trying to keep this under the $900 range. The first way i wanted to go was with an Intel i3 3570K with a Geforce GTX 480. Then i saw that i could make it much cheaper with an AMD A8-3870K with a Radeon HD 7850. I also don't know what motherboard to get, because there are so many, or which PSU to get. Any advice would be greatly appreciated!
