Should I get a mobo that supports both DDR2 & DDR3 and buy DDR2 for now and maybe upgrade to DDR3 when the prices come down??
Memory is probably the last place to spend lots of money. The difference between the high and low ends just isn't that much.

The smaller the switching speed the better. The differences are just not that great. IMHO, it is somewhat of a scam. DDR3 1866 (933 Mhz) 7-7-7-20 is the sweet spot. But how much worse is DDR2 1200 (600 Mhz) at the 5-5-5-18 timing?
I have the intel dp45sg mobo and haven't had a problem with it! I;m using an intel Q9550 and 8gb of gskill ram and 2 wd 1tb hard drives and has been a rock solid set-up! I think when I ran the test on memory timing it was 9-9-9 something! I think it's an awsome board but only been running it for a month. oh and the ddr3 1066 was worth it to me. The board seems faster then the asus pn5d which used ddr2
