Real men game on Falcon Northwest computers such as this one I configured for myself. Note the price tag at the bottom but this is the real deal, no compromises. Unfortunately, it does not run OS X so you will of course need to purchase an appropriate Mac for your needs as well.

This my friends is what a top of the line gaming PC costs not to be confused with something cobbled together with parts from newegg.com. This bad boy is a state of the art PC gaming rig.
Personally, I think the iMac is a better value given that it can also run games pretty well for most mere mortals and costs quite a bit less plus you don't need to buy another computer just to have a decent desktop operating system (OS X).
There are many things wrong with this post. The Quadro card is for programing and general utility, not for gaming. It has more horespower to tap into, but it's not optimized for games.
Further, each of those cards is near $4000.

Your supposed spec shows a triple SLI setup in a system costing less than $2K? .... you do the math.
