I didn't know there was so many expansion packs to dawn of war :O I might just have to play the game then see what happens after that
SoulStorm ( No4) is fairly new
Dark Crusade ( No3 ) aint THAT old.
I think its about 4 or so years old ( the original ) and in order to play it in all its visual beauty, you will need a half decent card too!
Winter Assault ( No2 ) is an expansion pack to the original so is not a stand alone like the other 3
SoulStorm is DX10 but there is no difference at all between DX9 and DX10 that I have noticed.

Actually, while I remember it...
If you install these 4 games in order, as I keep doing, then you will come across a small irritation as I have...
1 Install DOW and enter your DOW serial number
2 - Install Winter Assault and add the Winter Assault Serial number, but you wil also need to add the DOW Serial if you want to play with the Space Marines and Orcs in a Multiplayer
3 - Install Dark Crusade and insert the Dark Crusade Serial number...
... but...
If you want to play with the Eldar or imperial Guard from Winter Assault then you will have to add the winter assault serial number..
...And...
If you want to Play as Space Marines or Orcs then you will have to enter the Dawn Of War Serial number too!
4 - Install SoulStorm, and add the SoulStorm Serial number
...But...
Dark Crusade, Winter Assault and DOW serials need to be added too!
WTF?
This is only if oyu are having all of them installed on your PC and to be honest, I do like going back through them all just for kicks, and in fact, me and 2 mates only 2 weeks ago did a marathon where we played through the entire campaigns of all 4 games ( Space Marines on Original and Dark Crusade but Imperial Guard on Winter and SoulStorm ) and what a laugh... Took us 2 days non stop.
