Upgrading components = performance gain..?

I'd thought I'd already posted that correction myself, but hadn't. Anyway I can say that I've had it under 1GB in 7 64 bit, although it occasionally spiked above that. So back to the point of 2 is always enough for dolphin (although I always have 2GB of other stuff running, so need my 4GB).
