So I have an amd A10-5800k without a dedicated graphics card and I'm looking for an upgrade. The thing is the Ryzen 5 2400g with motherboard and 2x4 ddr4 3200 ram included is at the same price as the Sapphire Radeon Nitro+ RX 580 8 GB at a local store, I've seen what a 2400g can do and i'd guess is the safest bet since I don't really know how much the rx580 can do with such a weak processor, yet I still feel like buying the rx580 and then later on December or so replace the a10 with something better than the 2400g. What would you guys recommend me to do?
