If you're referring to outright compatability, it depends on the motherboard make and model, all you need is a free PCIe x16 slot, and I would highly suspect a 760G chipset motherboard to have one. If you have the PCIe slot, the GPU will fit in just fine. However you will need to make sure that you have an adequate PSU, with the appropriate connectors, and that the GPU physically fits in your case (if you have a small case for instance).
If you're considering how WELL they will work together, that's a totally different story, and is TOTALLY dependant on the application. Generally speaking they should be fine, but the FX 8320 is a dated model, and may hold you back a bit in some situations - This thread has already been considered here...
