Can the Intel Core 2 Quad Q9550 be a bottleneck?



I think it would be more practical than using the AMD A4 which is an extreme bottleneck
Playing Fallout 4 pushed the CPU to 100% and the GPU is just chilling at 14%
 
i just upgraded a computer with intel core quad q6600 and geforce gtx 750 ti , i tried it with battlefield 1 and it runs smooth on 1360x768
40 fps . it probably cant hander higher resolution though. setting the power performance to high made a huge difference for this setup
