wouldnt 6gb mean you dont get the 128bit thingie
as you cant get 2 pairs of 3gb ram. (or 4 pairs of 1.5) (or maybe you have 6 banks of 1gb? Unlikely though) (i like brackets
)
Anyways i think 4gb is the sweetspot for vista. like 2gb was for XP. Only serious CAD and rendering types need more than 4gb and those peeps will go for 8gb
