If my computer can run Warhammer 40,000 dawn of war can if run Warhammer 40,000 dark crusade?

heh of course...as dark crusade is an expansion it has to be the same graphics so yes you can run it.





also check this system rec. for it if your not sure:


Windows 98/2000/XP/ME, 2.0 GHz Pentium IV or equivalent AMD Athlon XP processor, 512 MB RAM, 3.5 GB free hard drive space, 4x DVD-ROM, 32 MB DirectX(R) 9.0b compatible AGP video card with Hardware Transform and Lighting, DirectX 9.0b compatible 16-bit sound card[3]
