Ok so I just bought Rust, Fallout New Vegas, and Chivalry Medieval Warfare. I can play fallout on my integrated hd 4000 graphics. My build is a i5 3570k 8 GB ram msi z77a-g43 mobo 1tb. No aftermarket heat sink and no gfx card. I can ya fallout fine but what about rust? Everyone is saying hat I should play it just fine on low settings. I get like 5 frames.
