So I'm wanting to upgrade a friends system to be able to run games like csgo,h1z1,Minecraft,gmod games like that, he currently has 8gb ram, an i3 4150, and some GPU (intel r HD graphics 4400?) Keeping in mind that he has an extremely low budget of about 100 euro, I was looked at something like an r7 240 or a really early gtx model? He didn't mind mind playing in low settings, thanks.
