They already tested single and dual CPUs and didn't show a difference between those when it comes to how much the RAM speed matters, and going to a quad isn't going to change things. Stick with the cheap RAM but make sure it's got some clock speed headroom - e.g., it's rated DDR2-800 and all your CPU needs is DDR2-667 or 533, and the latency numbers are reasonably low.

The 9450 is quite good, probably worth the $100 over what you can find the 6600 for, BUT under some circumstances it can be more difficult to overclock. The multipier is 8, not 9, so your MB and RAM need to support higher RAM/FSB speeds to achieve the same overclock.
