My questions are yes, I know with all the quad cores out and even the i7s possibly becoming mainstream, with the parts I have below on hand (left over from Christmas) how much improvement if any should I see and or which parts should I keep or not worry about putting into my current system.

I agree with Noya - not enough of a performance improvement to justify the upgrade cost.
The HD4850 and 9800GT are nearly equal in performance. PCIe v1 vs PCIe v2 isnt a factor in a single card system.
Overclock your E6400 to ~2.8Ghz on that Asus P5B Deluxe, add the 4GB of DDR2 800 RAM (or even 2GB of RAM if you're still on XP).
Look into overclocking the 9800GT.
WR2 seems to have the best answer, actually. If you overclock the CPU, all you really need to buy is a good CPU cooler which can also cool the other components as well (b/c of fan and the cooler's design)-that way you can OC the 9800 GT a bit more if it gets hot. The 9800 GT is OCable, so just do that. Also, you don't need to buy a new PSU this way, either. The best way to save money and upgrade your computer!
