hmm well i'm running on 8gigs... i don't even think i have a page file... i have so much apps open sometimes i scare myself.. but i say it's up to the user oui. i bought 8gigs of ram just for fun tbh... the programs i run are not demanding, and it doesn't boost gaming performance really for me. but with the prices of ddr2 being cheaper dan rice in china, and ddr3 falling like manna from the sky, maxing out on ram is surely gonna tempt you.
