I would like to build a new computer that would be capable of gaming at a high fps. I want to be able to use two monitors and be able to run many things in the background. I know I want to have a Intel I7 but I'm new to building and I don't understand how to find the rest of the parts to match this so everything is compatible with each other. The more options the better for me but I do need everything brand new. I am also not sure what operating system I should use.
