Question Need advice on new Motherboard/CPU Tight budget.

[Viper=tr=]

Need advice on new build. I have never built an am4 rig. Money is tight. Looking for a solid motherboard and getting a CPU with integrated graphics and upgrading to a decent gpu later on. My current rig is an Asrock 970m Pro.3 with HD 7900 series GPU.
Figuring CPU with Integrated graphics would be better than my current GPU. Is this correct or should I stay with my HD 7900?
I read Integrated graphics CPU's cause bottle necks if you add a GPU? Is this correct?
It gets overwhelming trying to figure what CPU works with what board.
Was thinking B550 with room to upgrade. Be nice to have a board with some nice bells and whistles that I could overclock down the road once I got comfortable with it.
Eventually get in to some gaming within the next year.
Any advice?

Most of new APU processors are now better than those ancient GPUs. Not all Ryzen up to 5000 series have any IGPU, only those with "G" as suffix. For instance r7 5700G which would be a good fit to b550 MBs.
Which exact HD 7900 do you have ? they range from 7950 to 7990 and difference is large.
To find which CPU "fits" in any MB, you look at it's QVL list for CPUs, it will tell you which BIOS version is needed for any Ryzen CPU. You may need to get BIOS updated to use 5000 series Ryzen. With G processors you need fast RAM because it doesn't have own. 2x8GB of 3200MHz RAM is best shoe in.
