Well my point was that even if it’s not out for OS X, the Mac computer is a very capable gaming machine if you don't want to wait for the port.
But under OS X ported games I've played Ghost Recon, COD1, 2, 4, Battlefield 1942 & 2142, Bioshock 2, AOE3, Assasins Creed series, Splinter Cell Conviction and others; all very enjoyable response times in high to max settings.
As far as highest $$ can buy, my son is still gaming on our 2008 24" iMac. Even for the 10+ years I was gaming on DOS/Windows, the machines to have were the latest greatest CPU/GPU's that cost 2-3x the average PC on the market. Unless you didn't mind playing at average or below average settings, which is exactly how THE AVERAGE PC user plays (that plays games) because they don't upgrade every 2-3 years to stay on the bleeding edge just for game performance.
I played Wolfenstein 3D on a 386, had to go to 486 to play Doom & Duke Nukem, then to Pentium class to play MechWarrior2 and Quake, then to Pentium3 (or 4?) for Ghost Recon (that was the game I transitioned to a Mac G3while playing). Same old same, same old regardless of OS.
I've been gaming on OS X for over 10 years now, those who say OS X isn’t a viable gaming platform simply haven't tried it or are doing something wrong.
To be clear I'm not opposing you about Mac hardware, so I don't really see what's our difference here. In fact I believe a few handful of Mac computers could handle modern games just fine, as I stated earlier. A 2011 iMac with 6970M GPU is a decent choice, even outdated MacPro with Radeon 5870 or dual Radeon could still run games easily.
So yes, a few Mac products could be a versatile gaming machine, too bad many people only stick to their sleek looking Macbook Air now.
I was talking about the OS, you can buy powerful Mac computer, and you'd need Boot Camp Windows, or at least VMs installed to enjoy the fullest gaming experience. Sure OSX has a few ported games too, but most of the time it's always outdated big titles, or simply casual games. (Blizzard games are the only exceptions because they usually released on Mac & PCs at the same time).
And in my experience, graphics or FPS rates under OSX usually below what you could achieve on Boot Camp with the very SAME Mac hardware.
Plus how long until you're gonna see big player games as Battlefied 3, or Max Payne, or Mass Effect series to run natively under OSX, if ever? 4 .. 5 years from now? It's up to you if want to buy it years later, but hey ... on Windows it's already on the shelves whenever you want it. Run Boot Camp on your Mac and it's playtime!
Just imagine sir, if I only depend on OSX for gaming, it means the biggest games I ever played today on Mac is Black Ops, GTA III, Vice City, San Andreas, StarCraft II, Diablo III. I just can't optimize my hardware today, and so if I have to wait another 4 years to have 2012 big titles to be available on Mac, maybe I already sell this Mac and upgrade by then. This machine would never see lights of the day.
I just want to use my 2011 machine for 2011 games and a few years beyond, not for 2008 titles. I think that's why you bought a powerful gaming machine, even if it's a Mac.
