Premium: OCZ, Mushkin, Corsair
Quality: Kingston, Crucial
Bargain: Adata, Buffalo (good), Kingmax, Apacer.
There are plenty of other choices, but this is just a basic breakdown of different price points.
I dont really know if paying for the premium ram in a laptop is worth it since you cant even change the timings in most bios's. Premium ram is more for the overclocker in the desktop market.
I would go with whatever you can get for the best price (as long as its a name you have heard of) If it was a desktop you were talking about, i would say premium all the way.
And for the record, the 855 chipset in the 3790 wont recognize anything higher than pc2700. You can put in pc3200, but it only runs it at ddr333 speeds.
