Your clearly biased. Do you know that the opteron's and the X2's even have the same core for some brands
The 3800 can be overclocked fairly high and use the Manchester core if I'm not mistaken. The 4400+ is a Toledo core and is the virtually the same processor as the FX-60 and can easily be overclocked to the FX-60 levels on stock cooling (aka I did). The 4400+ can also be OC'd to the 4800+ levels at the same Vcore resulting in little to no increase in heat. I am willing to bet with some better fans you can push it even higher so please stop the hype as it gets fairly annoying.
Lastly the Opterons run at hotter temps than the X2s.
