[SOLVED] is it ok to buy an APU like the upcoming ryzen 4700G and add a graphic card later ,2-3 years down the line ??

Solution
I started running my system with just a 3400G but now run it with a RX 570. To be honest, I like the idea of having a iGPU with a graphics card, always good for a back-up if the GPU fails for some reason.
