Go with what you works for you, for me that's AMD, if you are into Intel, great. Remember, these are computer companies, NOT your family's honor 
Edit-You forget too, Windows 7 is NOT optimized for mutli-core CPU's, Windows 8 is/will be.
I just setup my new FX-8150 and have had a time getting it stable and keeping cool. I wanted to compare results with you I'm using a Noctua D-14 and its no match for the heat of the bulldozer. In gaming the temps are fine because it never goes far above 48c but under prime95 it will hit 70c!!! I had to really up the vcore because I have two cores prone to failing prime. I'm running at 4400Mhz 1.45v at the moment until I can get settle on a water setup that does not have loud fans. It will go much higher but for temps sake I'm keeping 4400Mhz.
