Ok so I am building a cheap gaming PC for myself. Initially I will just use the APU for my graphics card to cut back on my initial investment, but later down the road I want to purchase a dedicated GPU. What is the sweet spot for the processor I have chosen? I don't want something that's overkill because the processor constantly bottlenecks, but I also don't want to leave any extra FPS / visual effect on the table by picking a weak GPU. I guess I would rather side towards a GPU that's slightly overpowered for the APU, rather than the other way around. Anyways, what would you recommend?
