Can I replace an APU if I already have a GPU installed?

I've been using the APU that came with my PC (AMD A4-6300 with Radeon HD Graphics) as my CPU. I recently got a NvIdia Geforce GTX 750 to replace the integrated graphics.

My question is could I completely replace my APU with a better CPU seeing how I have an actual graphics card?
