I am running a 1.1 athlon with 512 Ecc sdram. I recently turned green with envy at my M8's 1.4 256DDR machine, the load ups were way quicker the 3Dmark2001 way higher yet my friend is now wishing he held off with the DDR machine as the thing has been back to the manufacturer twice both times with memory related problems. DDR is quicker but it loses with reliability. It needs more reinstals and higher maintenance. I was going to upgrade the motherboard and processor in the Spring but I think I will save some money and get another 512 SDRAM keep the motherboard and only get a new processor.
