Ram Selection Question

I was wondering what would be better for my a64 system, which will mostly be used for gaming and music There are so many selections i could make with the setup. I could get quality 2x512mb sticks for around $220, or I could get 2 x 1gb sticks for a little more. Heres a couple items I'm looking at. This is my first build, and I am interested in learning to overclock as well. Thanks for the help.

If your just gaming and music, there's no need for 2 gigs. 1 gig should suffice, and both the rams you listed are good.

Welcome to the forums !

Right now, you won't need more than 1GB for music and games. And 512MB DIMMs will overclock better because of the lower density RAM chips used. In a year or two, you'll probably want 2GB, but but you could always add another pair of 512s.
