Thanks for the quick reply! I wasn't too sure on the Kingston RAM because I was a bit wary of the low price. Not that i'm one to say that just because it is cheaper it isn't as good though!
So the Dominator RAM is probably not the best choice at 3 times the price of the Kingston RAM. If you were wondering why I am only after 4GB its because i'm still stuck on the ancient OS known as XP
Since there is no "Upgrade" as such to windows 7 i'm not in the mood to try and get everything reinstalled the way I want
Still the motherboard should be ok for future RAM upgrades when I finally bit the bullet and install a fresh windows 7.
