I am new to gaming computers so be patient with me haha. I am wanting to build the best gaming computer possible for around 900 dollars (do not care about blueray and all that crap, all I care about is pure performance for gaming) I also would like to exclude the OS, keyboard and mouse. I just want to have a custom built machine that would last at least 2 years, if not more. Right now I am gaming with a Dell Inspiron 1545 so you can imagine my frustration lol. I am going to attempt to build this computer myself, I just have no idea what would be the best bang for the buck. Again I am new to all this so just try to be understanding Thank you!
