So I reluctantly and excitedly pulled the trigger on a new 15" Pro. Ordered this morning and just picked it up! I've been dying to see more benchmarks on games, and I'm super excited to get on it. Some games I actually play that I'll test in OS X until I get Windows on there later... Diablo 3, Starcraft 2, Heroes of the Storm, Borderlands 2, and several other random games I have. Mainly the Blizzard games though. Installed the 10.10.4 beta since it was having wifi issues, hopefully that helps. This will be quite a step up from my late 2013 model with only Iris Pro graphics. The 2013 wasn't able to handle The Witcher 2, very excited to play that as I beat the first one. Heroes of the Storm: 1080p with high settings. Ran perfectly smooth, frame rates were usually 50-60. Diablo 3: 1080p with highest settings and shadows turned off, no AA. Did a run for the keys in each Act on Torment 6, only dropped below 30fps a few times in huge battles. Otherwise it was a buttery smooth 50-60fps. Borderlands 2: 1080p with high settings. Runs perfectly smooth, looks so much better than low settings!
