Yes. It has only 8 HSIO lanes for GPU so I would not pair it with gtx 1080ti or better card but anything lower will work fine.
Edit: 8 of course, mistype.

Raven Ridge is PCIe x12 (x4 used by the chipset, leaving x8 for the GPU).

If someone has the money to plonk on a 1080Ti, I'd hope they can afford a better CPU. That said, I'd still be curious to see how far the 2200G/2400G can go up on the GPU ladder. None of the places I usually go to have explored that yet. Well, paying $170 for an IGP only to slap a discrete GPU on top right away doesn't make much sense compared to spending roughly the same amount on an 1500X/1600 + GPU.

That's an excellent question. IIRC, a lot of the CPU testing & benchmarks show it on par with the R5 1400/1500X, so you can probably pair it with just about any kind of GPU you want. You're right, though; if you can afford the 1080TI (especially at current prices), you can probably afford a better CPU as well -- & if nothing else, if you really need the extra PCIe lanes, given the same price you'd probably be better off with the R5 1400 than the R5 2400G.

But, I think these form a nice niche for those that want to have out-of-the-box decent gaming performance without having to also shell out for a decent GPU right now.

There are no extra lines, the IGP simply replaces the second CCX on the Infinity Fabric.

If the IGP used PCIe 3.0 x8 (8GB/s) to connect to RAM (25+GB/s), the IGP's performance would be horrible due to the PCIe bottleneck and 100+ns of extra latency for every access.
