Andy sptted one good point:
Personally I do not think that we will need more RAM than 6GB for the next couple of years.
But how will you put
???
The new mobos require THREE banks of the same type (not two like the older ones):
Therefore you can go for 3x1Gb DDR3 = total 3Gb RAM <-NOT RECOMMENDED
or 3x2Gb DDR3 = total 6Gb RAM <- RECOMMENDED
or 3x4Gb DDR3 = total 12Gb RAM <- if the price difference is negligable
