I am also assembling a new machine cant decide what i want...
If u are willing to increase the mobo budget u can also try the asus PB5 deluxe version but i heard its a bit fussy with ram
(well thinking about it, for that money, u would be better served with the Gigabyte GA 965P-DQ6
)
I checked the DS4 memory compatibility list from gigabyte site, no reference to G.Skill but u could find lots of models from the usual brands.
Said that i really dont see any reason for issues, but i will try to find some reviews on the board.
