I'm looking for (around) the best RAM I can get, at the best value. Now i've read the "pinned" post, but seeing as that I don't know much of anything, I shall post it here, and hopefully others like me shall benefit. Ok, I shall start with my local Best Buy. They're advertising "Kingston" 512MB PC2100 DDR RAM for $54.99 (after a $30 mail-in rebate). Also, they have the 512MB HyperX PC4000 RAM for $119.99 (after a $10 mail-in rebate). Now, i've got two slots in my system, so theres a good chance id get 2 (either 2 PC2100's, or 1 PC4000 and a PC2100, obviously because of the $$. So thats what their advertising, but hopefully you guys could give me some other ideas on something cheaper/better. Thanks!
