Running down my personal gripes list:
Square Enix takes forever with FF games, but they do show up. Cross your fingers to play FFVII:RE in 2021 on PC.
Waiting for new Yakuza/old Yakuza is an ongoing process (+Judgement), but they'll all be on PC one day.
Anime fighters made by ArcSys and French Bread take too long to come over after launching on console, and launch in a confusing state with a split playerbase (Xrd Sign, Xrd Rev, Rev 2 being DLC for REV). Under Night has done this song and dance bullshit like 3 times now, who knows if the newest console UNI game will come to Steam. New GG is currently uncomfirmed for PC.
ATLUS sucks and gives no fucks, period. Don't count on anything Persona. It's so bad that the two PS3/360 persona fighters are actually PC based in arcades but haven't come to Steam - now some of the sprites only live on in Cross Tag Battle.
Otherwise, you're golden. Loads of smaller titles are abundant, and probably don't even need such a high spec PC (of course that may change over the next year or two). Namco Bandai is usually excellent, CAPCOM is also usually excellent. Tecmo Koei ports their titles to mixed-positive results. SE is much better with anything not FF. There's a billion Nep games. All the Souls and souls likes are here. Killer 7 HD is only on steam currently. Travis Strikes Again just came out.
Depends on what games you like, but you'll most likely be satisfied.
