Yeah, future proof is an overused term. But the 939 platform actually does have a lot more branches than the 754 platform, with offshoots that will continue to grow for at least a year or more.... for instance: Dual Core, PCI-E, and SATA2. Also while 130nm chips don't run extremely hot, 90nm run even cooler by -5/10 degrees. Incidentally, after my using the Nforce4 chipset for five months, I've found it's remarkably mature, robust, and stable.
