Budget Gaming System Approx. $650

Building a new rig with a price tag of $650 in mind. I game, but don't need the latest technology to run fps games(don't really care for them). More along the lines of rts, strategy games and the like. Should I drop down to the DDR2 version mobo to save some money? Not really sure how much performance gain I get from the DDR3 version(more overclocking headroom?).

I plan to overclock, shooting for 4ghz as dualcore, and if I am lucky will unlock and shoot for 3.5ghz. Looking to buy anywhere between now and the new year.

Will add in a generic dvd drive for ~$20.00

Most likely using win 7, not including the cost in this build though.
