It's not a quad...
True, it's not a native quad, but you still get 4 logical CPUs.
dont we have an FSB n these I series processors
The Intel "Core" (ie i5,i7,etc) uses an integrated memory controller so you don't have a FSB to communicate with the NB. However, you do have a QPI (QuickPath) which works similar to the HT(Hyper Transport) on AMD CPUs.
