Quick question, with RAM coming down in price more and more, i was wondering if 8gbs of PC2-6400 on a DFI X48 based board would be stable, with more ram would a workstation bored be better advised? or will DFI's X48 boards cope. The CPU will be a intel quad core incase people were wondering. Or is there any point getting PC2-6400 ?? is a higher speed RAM like PC2-8500+ going to add a huge preformace margin? Im not intrested in DDR3 as the price is extreme and very few motherboards have support atm as far as im aware.
