You all are high. My Xeon W3680 and 5870 is the fastest "gaming" mac you can get right now. Period. That does not mean it is the fastest gaming PC. You can build 1500.00 PC that blows it away. The graphics in Mac Pro are 50%-100% faster than the top shelf iMac and the processor is basically an i7-980x. Xeons are no slower in real life than the i7 counterparts (I have ran most of the benchies that prove this) they are just better quality and can take more punishment. Overclockers love them. And the 6970m on that 27" imac can barely push the native res on Call of Duty MW1. Such misinformation. My Mac hits 22000 in 3dmark Vantage, 23900 in PCmark06 and 10622 in Passmark. What's the iMac get?
But still for pure gaming and that is why you want a computer, build a PC. Much cheaper and upgrades are easy and readily available.
Well said. Now end this thread.
