The Witcher Enhanced version, Dragon Age Origins (much better gameplay than console versions), Mass Effect saga (better gameplay than consoles too). I haven't tried other bioware rpgs yet (Neverwinter Nights, Baldur's Gate, KOTOR) but they are pretty famous for a reason, right?
I tried Shogun 2 demo and I'm getting it.
Finally, this might help. It is a similar thread I made when I got my new desktop pc asking for pc jewels.
