Hi all. I've never built a gaming PC before but have used a non-gaming PC to play games. It obviously isn't designed for this, and my FPS is very very inconsistent in almost all instances. I'm hoping to build a gaming PC, within the budget of £600 - £700. The most likely games this would be adapted for would be Overwatch, Starcraft II, Minecraft, e.t.c, but I would like it to be relatively future-proofed, although this isn't the most essential aspect for me. The case can be cheap and non-flashy, I'm looking for more function over fashion with this. Provided it works for the games I enjoy, three examples of which I listed above, then I'm happy. The screen I use currently has an HDMI port, so component suggestions that work with that would be excellent. Keyboard, mouse and other accessories aren't required; I own a keyboard, mouse and competent mic, and as I said, function over fashion, so they don't really need to be replaced. I use a 23 inch HP monitor with resolutions 1920 x 1080. Thanks!
