Hello, I've been browsing around for parts lately but I can't decide what to choose. I have my main rig all good to go with a GTX 780, but I need to build a $600 gaming rig for my friend. He's been saving money for a while to get it. I already have a mouse and Windows 7 Home Premium, but I need the rig to include a monitor and keyboard since he's coming from a laptop. He plays Minecraft with tons of mods primarily, but he wants to play tf2 and titanfall as well. He doesn't care much about graphics quality, more about performance, and doesn't care about size of the monitor, as long as it isn't "laptop size" (17 inches or lower). As for the form factor, I think mATX would be best for him, and the cheapest case I could find was the Fractal Core 1000, which is fine with him. I'm lost as to the rest of the build, but I'm trying to stay away from APUs because Minecraft is more CPU intensive, and I want him to be able to upgrade graphics if he needs to, but this can hold him for a while. Thanks in advance.
