I thought about upgrading but considering usb 3x 10gb and and ci express is around the corner I might hold off. I know ddr4 and pci-ex 4.0 is a year or 2 away, but those are all luxury technologies seeing as nothing can take any advantage of those technologies for long time, esp when pci-e hasn't been saturated yet on a single gpu card and no cpu has come close to tapping out ddr3's capabilities. other then lower v for mobile devices there is really no reason to upgrade from ddr3 ddr4 for anything else. but pci express is really needed and usb 3 10gb would be needed to transfer really large files.
I think the main point of APU computer is its cost effectiveness.
Despite having integrated graphics cheapest of am3/am3+ motherboards cost less than cheapest fm2 motherboards. Not even that, the cheapest APU processor costs less than the cheapest compatible mobo.
AMD please stop this pricing weirdness. I really don't care if they launch 4 way crossfire and 10 gigabit lan mobos for APUs.
