I'm looking to build myself a new computer. My budget is (a maximum of) $550. I currently have a GPU (Radeon 7850), monitor and a PSU (Corsair CX600). This will be primarily for gaming and I'm not set on whether I want to go Intel or AMD. I have no experience in overclocking, but I can certainly learn how to, in order to maximize any components that would allow it. I will need an OS (Windows 7), as well and would like components that can be easily upgraded in the future. Thank you guys in advance for all of the feedback.
