If you're worried that your computer can run any game just use
this website, it scans your computers spec and tells you how well it could run the game, I believe they have Warhammer online up. and as a side note, consider this if your worried about the quality of the game when released: Total space WoW including my shit ton of mods and patchs: 9.96 GB, the amount of space Warhammer Online takes without patchs or mods type: 9.64 GB. Not sure if it matters THAT much, but to me I think it's gonna be good.
