Unfortunately I don't. In Oct 2013, I built my PC for $1000 (see signature). At the time I could of purchased a Digital Storm computer with virtually the same specs for about $150 more. You might be able to find a local computer store that builds computers for the same kind of prices.
Don't get me wrong, I love my Mac and the MacOS, although I'm not happy with how expensive they are. I'm really irritated that my last lap top cost $2000 when $1000 PCs can run circles around it for gaming. And Mac prices, instead of going down, have actually gone up. I had been willing to pay $2500 for my 2011 MBP that had dedicated graphics, but this time, the price jumped to $3000 and I said no frick'n way and still ended up paying $2000.

However that $1000 I saved will go along way for my next PC!
Based on my experience with Macs and PCs over the last 27 years, strictly for gaming, for a variety of reasons, the PC or even console are a better choice for gaming. You can buy a MacBook Air for $1000, and a gaming PC for $1000 or a consol for $400 and still spend less than the single purchase of the top of the line MacBook Pro with a dedicated, mediocre graphic card for $2900. Being in the PC environment, you won't have to wait for games to be ported, with lesser features, and in some cases with limited or non-existent cross platform multiplayer.
Apple's plan for VR is interesting, but having to purchase an external GPU in addition to the expense of Mac hardware?

That just does not sound competitive. I'm hoping Apple gets a rude awakening from their base and sees the light.
