Computer build.

Well I was looking for help with my first computer that I'm going to be building i was told that it is a cheaper method of getting a high quality gaming experience compared to buying alienware or something of the sort.
Now I needed some help in choosing parts I want the most powerful machine that I can buy with a 1000-1100 budget I will also ask for suggestions on cases and monitors.
All help Will be very appreciated.
Also please post all suggestions or maybe pm me the build that you think would best fit my needs.

 

What currency? What type of games are you wanting to play? Does the build include a monitor/OS/mouse/keyboard?

What country are you in? Some sites don't shit to certain countries.
