My friend is looking to get into pc gaming and I've put together a build for him. All that is missing is peripherals like a mouse, keyboard and monitor aswell as windows and most importantly a gpu. He's looking to play all games on at least medium settings and will upgrade in the future. I'm not sure which gpu to slot into the build and he has a budget of around 500 euro. Please suggest any changes that would help the budget and performance if possible. He has a budget of around 500 euro. Thanks. http://pcpartpicker.com/list/rFPC3C
