In that case, pass in a GPU altogether. Get a A10 7850K (which actually has a iGPU that's better then a GT 630 which is enough to play BF4 and modern games on low) and when you have the cash, buy somthing like a 760. Then, you'll have a better CPU and GPU, it'll just take a few months longer or however long it will take for you to afford a GPU.
