Your PC will need a graphics card thats as powerful as a GeForce GTX 650 2GB/Radeon HD 6970 and it should be paired with either a Athlon II X4 631/Core i5-655K 3.2GHz CPU to match the Rambo recommended system specs. This PC setup will deliver 60 Frames Per Second on High graphics settings on 1080p monitor resolution. Rambo needs a Radeon HD 2350 Pro graphics card to play on low settings, with a Core 2 Duo E8300 2.83GHz or Phenom II X2 511 processor to reach the minimum specs, achieving 30FPS on 1080p monitor res. You should also have 2 GB system memory for min specs. You will require a DirectX 10.00 GPU. To summarise, Rambo needs around a 10 year old PC to play at recommended settings.
