Yeah, my PC definitely won't run Witcher 3... But as I said, somehow I'm not drawn to these games. Is there anything else?
If you enjoyed Skyrim, probably Fallout 3, New Vegas or 4 will be pleasantly familiar and RPG-lover friendly. Especially 4, from what I hear, which has much more in-menu customization type things which are the hallmark of really intensive RPGs.
I tried playing Dead Island, don't know if anyone else here has. I thought it sounded fun because it was supposedly 'open world' like the Fallout games and others, but somehow it was just not quite what I was expecting. The animation and everything is way nicer than the Fallout franchise (prior to Fallout 4, at least) but you can tell the scope is way smaller and there's just not as much junk to pick up even though there's crap everywhere that looks like it ought to be collectible, and the premise is totally whacked (you alone have to be responsible for saving about a dozen other people, not one of whom is willing to accompany you. Even Fallout 3 let you have one companion, and New Vegas let you have TWO!) I also found combat imprecise, the zombies move erratically so that even fighting one is a chore since they can easily side-step you and attack, and that's not even considering a group attack. Atmospherically, I'd say if the Resident Evil games were anything like that back in the day, I might still be playing them now, they really nailed that part, and that it's on an isolated vacation resort island is a nice touch. But that there's no way to save the game except for checkpoints (what genius came up with that notion?) and your extremely limited carrying capacity which is almost ludicrous due to the fact that many different healing and weapon items seem to respawn after no time at all, make it too flawed to pursue. I can see how others might enjoy the hell out of it, I almost did myself, but too many deal-breaker type designs just made it impossible for me.
