berbaloi tak kalau tukar E8400 ke Q9550?

RM720 utk Q9550 retail baru
RM650 utk i5 750
so mcm mana??hehe

Both are point-to-point interconnects. DMI is actually based on the PCI Express implementation and doesn't actually carry any PCI Express lanes as some would think the PCI Express controller on the LGA1156 CPUs actually are integrated into the CPU die. The DMI connection is only connected to what was once known as the southbridge, now called Platform Controller Hub.

The QPI design is very very very similar to the AMD-backed HyperTransport (an industry standard point-to-point interconnect designed by the HyperTransport Consortium in which both AMD and NVIDIA are a part of) based design, whereby the memory controller is on the CPU and then the QPI would have a point-to-point connection, once again if I remember correctly is also somewhat related to the PCI Express specs. This would talk to the chipset or Northbridge. The Northbridge itself hosts all the PCI Express connections and other chipset functions.

The Southbridge or the Media Controller Hub is connected to the Northbridge via a DMI connection ... which if you only look at a block diagram, is exactly how AMD has been doing their chipset designs since the K8.
Technically the QPI is faster, but that's really up to how fast the integrated PCI Express controller can interface w/ the cores on die.
