I was checking for this game as well. I've been "A PC" since 1980 but last fall switched to Mac - then a better Mac once I learned how superior they are to my PC's.
Anyway - I prefer gaming and using the iMac. I have (upgrade the duo core for this quad core) 27" near retina display. and 6970M graphics card. I can't get bootcamp installed. My machine has 500gb SSD and 2TB internal so it doesn't like bootcamp. I have external DVD and it gives me problems with trying to install my Win8 original. After 3 days (And I'm a computer geek) no go. So I'm limited to using PARALLELS (not mentioned in the thread so far but AWESOME).
As to WINE - you get what you pay for. ITS FREE and (it sucks) it can run "some" pc games but with major performance hits and much tweaking. I have some wine wrapped games that will play on my quad core 3.1- 12gb ram. But I really dislike wine and cider. They are LAST RESORTS.
I run lots of games in parallels. I installed it and win8. I can run the Mac and Win8 at the same time - in full screen or side by side in windows. I can even run a Mac game and a PC windows game SIDE BY SIDE and have done it in super high res and posted a video on you tube. (Runnning F1 2012 on win) and Borderlands 2 on Mac both side by side running 60+ fps.
Parallels was on sale for 50 bucks a couple weeks ago. Still normal price is a very fair 79.00 or so.
A few PC games I run..
F1 2012
Warhammer 40k (space marines)
Call of duty Modern warfare 3 OMG this is good
Sailing simulator 5
Virtual Skipper
MASS EFFECT 2
Contrast
Call of Duty Modern warfare 2
Medal of Honor (also great one for a oldie)
SKYRIM (not one I like)
Assassins creed II
Because some don't work - I like to try a demo of the game (often from STEAM) first. I did this with Mass Effect 2. The demo ran fine so I bought the game. I also bought on Steam Tomb Raider but a week later it was released for Mac so I re-downloaded Mac version and deleted PC version - though PC version ran fine.
I'd like to try any of the CRYSIS games. But they either have to be on STEAM CHEAP on sale... or I need demo. Of course if they don't run on the Mac with Parallels I can always run them on one of my PC's. But I don't use those much so they're downstairs and I like to game on the iMac which is upstairs. I use to be a beta tester for Activision (paid with my name in the credits) I've also beta tested for Microsoft a bit. I've owned about 20 PC's (most built up by myself) since 1980 and said I'd never get a Mac. (I was given one as payment for a job I did) and a week later... I was hooked and I'll never buy another windows box.
Most everyone that I know who is (into computers pretty heavily) has gone Mac. I was told after a week of frustration I would be hooked. and they're right. I've been a Mac now since last summer.
