As for everything above me&er, sounds great and it's a good time to buy, and I've heard only good things about the cheap Geil 2GB PC6400 kits that OcUK are selling atm.
Luckily I've never had even a sniff of a stability problem with Sata AHCI setups in Vista (done about 6 installs so far, all with Seagate drives though), what I do get on my Laptop though, is every time I install a new Intel ACHI Sata driver my Vista needs to be activated again, sometimes it just works over the net, but sometimes I need to ring up and give the cheesy excuse.
