You buy an APU because you like the included graphics and have no plans for a discrete graphics card upgrade.
In such a case, you would be better off spending on a stronger cpu in the first place.
You know, of course that you also need to buy a new motherboard and DDR4 ram.
If budget is an issue, consider a intel G5400, a B110 motherboard and 2 x 4gb of ddr4 ram. It should cost about $200.
Your dual thread E5300 has a passmark rating of 1540; that is when all threads are fully used.
It has a single thread rating of 1050. That is what most games depend on.
The 8 thread ryzen 2400G would be a nice improvement. Passmark is 9289 and 1919 single thread.
A very good choice if you will also be running multithreaded apps.
For games, not...
