The performance was where we'd expect a DDR3-1600 kit to fall. My PC feels snappier and more responsible. I don't have the pesky lagging issues because Photoshop has chewed up more memory than my old 2GB system could provide. If you're building a new machine and DDR3 is the way you're heading, I would consider picking up the Aeneon XTune DDR3-1600 4GB package. It may cost more but with Windows XP on the way out and Vista being the primary Microsoft OS, you'll want the extra bit of memory.
