Yeah, thats what it is. There is no northbridge anymore, hence why we have now SLI/Xfire compatability.
On 775 boards the North Bridge or MCH was the central point of traffic between the CPU - Ram - PCI-E and communicated with the South Bridge that handles HD's - USB - USB etc. There was also a memory controller on the boards...
Now the nb/mch has been implemented onto the cpu, so we have a CPU that handles the communication from Ram & PCI-E.. As well as an IMC (integrated memory controller)
Faster Bclk = faster system, just like faster FSB = faster system.
Also things of interest are there are slim chances of you damaging the motherboard by overclocking, aside from the bad Foxconn sockets, which I think have been pulled by most companies.
But the chances of us breaking the cpu has gone up, with everything on the cpu, overvolting and running at high temps are still in the trial and error states.
