Thanks for all the advice. The intel motherboard I have uses 168-pin memory. While still available, I've only seen it online. The board will support up to 3GB of ram, so I'm going to load up. Unfortunately, the biggest sticks I've seen at newegg are 512MB sticks, so it looks like I won't be able to max out. I'm trying to run Fallout 3 without having to pop for another machine. The computer I'm currently posting on (wife's) will run the game, though slowly. This one has a dual core processor, where mine doesn't. Maybe I'll load both machines with memory and swap with her.
Wonder if she'll notice?
