Mac Pro. Buy it as an expandable creative platform if you love making movies, photos, doing graphic design, rendering and shit and maybe play an occasional game. But for the love of god if you want to play games don't buy one. That means running windows and why would buy this kind of hardware designed for a operating system that isn't particularly games friendly. If gaming is your thing buy the highest spec PC you can afford. You'll get a lot more performance for your dollar by buying a standard consumer level hardware platform then a professional workstation let alone an Apple workstation. Also graphics cards for the Mac Pro are hella more expensive and still second to what's available for PC.
