I want to build a budget gaming pc that can run BF3 and Crysis 3 on mid-low settings and I still have not found a graphics card that suits me perfectly. I want to spend around £100. I have found the nvidia gtx 550ti but it is £80 and I haven't found another decent card for around £100. There seems to be a big price jump from the 550ti to the other cards. Please help me find the right card
