You just need the GPU to support OpenCL and be supported by Hashcat, i.e. pretty much any recent good GPU 
For example the GPUs that people discuss and benchmark here, or you can ask about a specific GPU if you are not sure.
It's actually better that Hashcat does not see your CPU anyway: on my system built around an i7-7700K and a Titan Xp, Hashcat is slower when I force it to use both, using the Titan Xp alone is faster
