Type of RAM to Get...

I already have two sticks of 512MB PC2-4200 533MHz which equal 1GB. I was wondering if I should go with a 1Gig stick of RAM or get two more 512MB sticks? And if so do you recommend any that are fairly low in price but perform well, preferably anywhere from $50-$90.

Go with 2x512 of DDR2-533 value ram. If you get a 1gb stick your dual channel will be diabled & cost you 5-10% in memory performance.
