[citation][nom]Taft12[/nom]Mixing motherboard and chipset techs has worked very well in the past (AM2+ -> AM3) and not-so-well,[/citation]
AM2+ > AM3 is a planned and official upgrade path from AMD. Thats a LOT different than taking a chipset such as the P67, add other chips to allow for PATA and PCI slots. One of the problems with the P35 board (and other intels) in which the chipset did away with PATA and a mobo manufacture would ADD a PATA controller because the Optical drive market was still WAY behind getting onboard with SATA.
So... this (A) raised the price and complexity to the board (B) caused compatibility problems if the PATA was used - such as RAID failure or performance problems. Meanwhile, AMD Chipsets *STILL* have native PATA controllers and don't suffer from these issues.
Or some past ASROCK or no-name brand boards in which they'd Frankenstein parts. ie: 486CPU on a 386 chipset, VLB and PCI on same board, AGP with PCIe board (They typically routed the AGP slot into the PCI bus = VERY POOR AGP performance. Only 1 board out there had a real AGP slot with PCIe, kinda $$$), add-on CPU adapters to plug a non-compatible CPU into an older board for more performance (very old school).
In my Amiga days, I did use a CPU adapter to double the performance of the system, and it had a plug in for the original CPU and a switch for compatibility... $50 or so. But some made for PCs were $100~200, but back then you were paying $2000~4000 for a PC desktop, so dropping $500 to use a new type of CPU might have been worth it, even thou the desktop couldn't use the full function of the CPU. That kind of stuff, I never full agreed with.
