My 3 year old laptop finally hit the bucket... it doesn't start anymore. I didn't realize how much I relied on it until it was gone and now I'm ready to get a replacement. I hated the fact that I couldn't play any 3D games on my old one. So I would like the new one to be able to game decently... like play Half-Life 2 or something but nothing too powerful. Also price comes into mind... $600 will be the max I would want to spend. I would also prefer it to be a Core 2 Duo, but I searched a little and they seem to be quite expensive. Anyone have any good links? I've only searched Dell as I heard they have pretty decent laptops.
