Intel DP45SG

[Guest]

Is Intel DP45SG a good mobo? Is DDR3 worth the money? 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??

Yes.

Is DDR3 worth the money?

DDR3 with low timings, CAS-TRCD-TRP-TRAS = 7-7-7-20, probably.
High end DDR2 is in the same class http://www.ocztechnology.com/products/memory/ocz_pc2_9600_low_voltage_blade_series

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?

Maybe this will help. http://www.tomshardware.com/forum/261471-30-1066-motherboard

Dual channel memory allows two memory access to take place concurrently. Triple channel allows three concurrent memory operations.

Intel Nehalem (Core i7 processors) separated the memory access from the front side bus (FSB). With your board, memory accesses are competing with graphic updates on the FSB. Something to think about.

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
