Notes: This rig is getting older. It was quite an ultimate build back in 2014 when I built it; at the time an absolute beast spec-wise. It still serves me well, and although it doesn't run everything on ultra settings anymore it still plays any modern game fine.
Although, to be honest, I'm looking at upgrading or maybe doing an entirely new build. Because in March we'll get a new Half-Life game. And that is a perfectly valid excuse for getting an Index. But to properly drive that headset, I'll need some more upgrades...
