Help me build a new rig

I've been doing minimal research on building a new machine and this is what I've come up with so far - can anyone lead me to any better advice? I know the Nehelem chipset is coming out but I don't care right now (there's always something better coming out). Mainly - you think it's worth spending the money I am on the mobo for the DDR3 support? Thanks for any help!

for your budget don't get DDR3 its not worth it yet.

also i recomend getting a more brand name PSU like a corsair or the Cooling and Power 750

and for videocard a recomend and HD4850 cuz your mobo is not sli compatible

thanks for the advice! Looking into all your recommendations now. Appreciate it!!deanbigbee

Just some recomendation, you can figure out where you want to put your money into but i recomend a good mobo with an decent upgrade path.
