I'm thinking about going to my system maximum for memory (8 GB).. but I honestly think I don't even need to. I get amazing performance out of the 5 GB I have, and it never gets near 50% used, so maybe it's a waste of money.

Yeah.

Speaking of which, I just learned the HP Pav A6702f (1 model better than mine) can support up to 16 GB. WTF HP? Way to double up on me after a minor model update a few months after I buy mine!
