I have an amd radeon 8570d graphics which is apparently connected to the processor so I want to get a better graphics card latter and was wondering how I would change it or would I have to get another processor or can the gpu pop off and be replaced

No your APU does not support higher end or the newer R200 line of graphics card. The older model APUs is only compatible with 6670 or 6570 model GPU chips called Turks (40nm). Not even the 6870 Barts will be compatible only Turks GPU.

The only APU model that can be upgraded to the newer R7 gpus are the newest A10 7800k Kaveri series that comes with R7 line of graphics. They use the same gpu chip from HD 7870 or 7850 Pitcarn. The R9 270 also uses the same Pitcairn model but is...

The R9 270 also uses the same Pitcairn model but is called Curacao because of the 15% increase in power and performance than 7870.

Even if you can crossfire the iGPU and the dedicated GPU I would advise not to do it because almost always the dedicated GPU is stronger and faster than iGPU's which crossfiring will only be detrimental to performance.

Also APU's are not strong in terms of performance in gaming so your processor will bottleneck the dedicated higher end model of GPUs unless its the A10 Kaveri which has considerable performance.
