The Most Wanted Processor On The Planet is : AMD Phenom II X3 720 or 710

If you look at the specs and price is quite normal
if you consider 3 core something usual :) but if you have an AMI bios
and I do have one I can Upgrade from Triple core to quad for Free
Here is the howto : is just an bios switch
ahh and the 6M of L3 cache is sweet

But there are chances that you will be left only with an simple Triplet if
the bios doesn't enable you the Quad inside
It is not guaranteed that it will work with all motherboards with AMI bios
