No Mac = Dumb statement! I have an 8 Core Mac Pro, cost 2500.00 USD. I added 12 GB memory from Newegg, and run Bootcamp with Mac OS and Vista Business 64-bit (needed to see 2 CPUs). This Mac Pro is THE most stable PC I've ever owned.

Present inventory: 1 8 core Mac Pro, 3 Quad Core PCs, 4 laptops (3 Core2), 1 Dual core, and 2 single core PCs -- all running Vista or XP Pro.  The Mac is the finest hardware I've ever owned.

Check out the new Mac Pro 8, core + 8 Hyperthreads (2 x 4 core Xeon “Nehalem” processors). For 3299.00 USD, it's the rapid-render monster. Try and build that configuration for those $$$.
