I have an Alienware Aurora Ryzen Edition R10 with a NVIDIA GeForce RTX 2060 6GB GD DR6, 16GB or RAM,  AMD Ryzen 5 3500 (6-Core, 16MB L3 Cache, Max Boost Clock of 4.1GHz) & Dark Side of the Moon chassis with Low-Profile Smart Cooling CPU Heatsink and 550W Power Supply.

I always have trouble trying to figure out which parts I can use with my systems. 

Can anyone tell me what GPUs I can upgrade to with my current computer? 

I'd like to get a minimum of an 8gb GPU.

Thanks!!
