The 7350k is a much faster CPU then any Pentium we recomend from the Kaby lake line and if you can get it cheaper the the G4620 which shares the same 630 graphics then that is a good thing (well assuming it works).
In emulation where pure single core performance is still king, it is hard to beat a recent intel processor excetpt with a better (and probably kore recent intel processor). For multi threading (which is important for pretty much everything else) it is getting closer and closer. So if you want to purely use the system for emulation then the 630 is good enough generally amd the 7350k's pure ipc is hard to beat. If you want to do any native PC gaming or well almost anything else, then the 2400g is probably the more generally useful all around option and much better for certain tasks like native pc gaming.
