Diablo III
You could argue that the Core i3-2105, at 1280x720 using Low quality settings, is somewhat playable in Diablo. The Core i3-2100 isn’t though, and neither Intel chip does very well at 1680x1050 or 1920x1080.
Meanwhile, both dual-module Trinity-based APUs do really well at 1280x720. They’re a little more marginal at 1680x1050. And only the A10 is really worth trying to play on at 1920x1080.
