why not get Macs for gaming?

You can easily get World of Warcraft, Quake 3, and many other games for the Mac. Plus there are a few Windows Emulators that run programs just like Windows itself with little or no bugs.
Meh, buy a smallish computer and get linux. Thats my vote
Even though I have an AMD Athlon X2 4200+ 2.21 Ghz Dual core (2CPU's), nVidia GeForce 7600 GT, 320GB hard drive, 5.1 surround speakers, 19in benq moniter with crisp picture, Logitech G3 Gaming mouse, 1GB RAM ... need I say more? Runs most games as smooth as if they were as old as Quake 3. I don't need to update it for another few years at least. Screw all your expensive computers. All you need is something small anyway. Mine costed $1600 and I couldn't be happier without it.
