Yea It's enough to play it, depends though what kind of card you have. Like if you have a really old card with 512, it might not work, though gpus that old prob didn't go up to 512. If there is not enough ram on the gpu then it'll "barrow" some from your regular ram.
On my old computer, my integrated graphics ran WoW, but not good, so I'm guessing any decent video card can run it at the higher options.
Also you double posted.
