i will use engineering softwares, CAD, MATLAB and such.. not just writing papers and Powerpoints >.<

now that thas mentioned, you can revert to using older versions of cad...maybe 2007-2008. I used them with a rig similar to yours.
Rig:
Intel E4300 (C2D @ 1.8GHz)
Intel DG965RY
Transcend 2GB DDR2 800+MHz overclocking modules
xfx 8600GT DDR3 Fatal1ty
250GB HDD WD
ODD
Thermaltake 420W PSU

^ this rig was during 2006 and it had no hickups with 3DSmax 9, AutoCAD 2007, Adobe CS3 Master Suite including 360' panoramic render tools. So your Quad will slice up all the work you throw at it.
DDR3 will be here for a while...as the new sandy bridge will still support that into the future, maybe 1.5-2 years.
Your machine listed above is ok, don't think abt DDR3 now cos getting a mobo that handles DDR3 will up your price and may be rare at this point for a C2Q proc.
